The mass of fuel in kilograms is 1.03 kg.
How do you calculate the mass of fuel?To find the mass, divide the amount of energy required by the amount of energy released per gramme of fuel. The kilojoule units will cancel out, leaving us with grammes.A simple multiplication can be used to calculate the fuel mass flow rate from the fuel to air ratio. The engine air flow rate is normally determined by nozzle conditions. The fuel to air ratio value can be used to calculate the engine's specific fuel consumption.
Steps of the equation:
The density of the gas sample in the canister is 0.710 grams/cm³.
We will use the density to relate the given volume of the canister (1.45 L) to determine the mass in kilograms of the fuel contained in one canister. We need to convert first the given volume in liters to cm³.
1000cm3=1L
The calculation will be:
Volume = 1.45L(1000cm/31L)
Volume=1.45×10³cm³
We can now determine the mass of the fuel.
mass = (0.710grams/cm³) × (1.45×10³cm³)
mass = 1.03×10³grams
We can now convert the calculated mass in grams to kilograms.
mass=1.03×10³grams(1kg/1000grams)
mass =1.03kg
Conclusion:
The mass of fuel in kilograms is 1.03 kg.

Calculate the maximum wavelength of light capable of dissociating the br–br bond in one molecule of bromine if the bond energy, or bond dissociation energy, is 194 kj/mol.
According to bond energy, the maximum wavelength of light is 614 nanometers.
We need to know about bond energy to solve this problem. Bond energy is the energy needed to bond other atoms in the molecule. To determine the energy in one molecule of chlorine monofluoride, we can use this formula:
E = BE / Na
where E is the energy of photon, BE is bond energy and Na is Avogadro's number (6.02 x 10²³ atoms/mol)
Now, we can calculate the shortest wavelength by using Einstein's equation for photon energy:
E = h . c / λ
where h is Planck constant (6.6 x 10¯³⁴ J.s), c is the speed of light (3 x 10⁸ m/s) and λ is the wavelength.
From the question above, we know that
BE = 194 kJ/mol = 194 x 10³ J/mol
By substituting the given parameters, we can calculate the maximum wavelength
E = BE / Na
h . c / λ = 194 x 10³ / 6.02 x 10²³
6.6 x 10¯³⁴ . 3 x 10⁸ / λ = 194 x 10³ / 6.02 x 10²³
λ = 6.14 x 10¯⁷ m

Describe How are
the two forms of energy
carried by waves and matter related?
the energy of matter implies the movement of masses, and wave energy has no moving masses
The energy of particles (matter) is the ability to do some work, so the energy can be movement in the form of kinetic energy or in the configuration of a system called potential energy, the sum of these two energies is constant.
A wave is formed as a result of perturbation of the medium by a substance, therefore, for the formation of a wave, a substance supplies energy, for example: in the form of motion, in the form of an electric or magnetic field oscillation, etc.
Waves after formation can move away from the substance that formed them, transferring energy that alternately has kinetic and potential energy, but the total energy is constant.
Therefore, the energy in matter is caused by the movement of the same, and the energy in the wave does not require the movement of matter, so this is a more efficient way of doing the work.
In conclusion, the energy of matter implies the movement of masses, and wave energy has no moving masses.

you've purchased a 12 ounce can of frozen orange juice concentrate at kroger. the instructions tell you to mix the contents of the can (the frozen oj) with 36 ounces of water (roughly 3 cans of water). name the solvent in this scenario
The solvent is water.
What are solutes and solvents and how do you differentiate them?
Solute-
A solute is a material that can be broken down by a solvent to form a solution. There are numerous ways a solute can exist. It could be a solid, liquid, or gas. The solute is broken up and distributed among its molecules evenly by the solvent, or substance, which causes the solute to dissolve.
Solvent-
Solvents are substances that cause solutes to dissolve and form solutions. Although it can also be a solid, a gas, or a supercritical fluid, we always find solvent as a liquid.
Given that 12 ounces of frozen orange juice is mixed with 30 ounces of water (roughly 3 cans of water), to understand this we can simply write
If 36 = 3
12 = ?
12×3 = 36×OJ
OJ = 1
,i.e, orange juice has one can and water has three cans.
1:3
Simply, orange juice is soluble in water because the solvent in this scenario is water. Due to its polarity and ability to form hydrogen bonds, water makes an excellent solvent, meaning that it can dissolve many different kinds of molecules.

What additional information, if any, would enable you to calculate the molality of a 7. 35 molar solution of a nonelectrolyte solid dissolved in water?.
The molality of the solvent is 13.8966 m
It would be necessary to know both the solution's density and the
solute's molecular weight.
Explanation:
Molarity = [tex]\frac{mole solute}{L solution}[/tex]
Molality = [tex]\frac{Mole solute }{kg solvent}[/tex]
The solution's density can be used to convert 1 L of the solution's volume into a mass solution. then the substance's molecular weight solute (given or calculated from the formula) can be utilized to change the number of moles mass of the solute in a 1 L solution using grams. The solvent's mass is the difference between the solution's mass and as well as the solute's mass (both of which have been determined). Replace the values and compute using the molality formula.
so the total mass of the solution is 934.4 g,
which leaves 934.4 g − 178.82 g = 755.58 g of
water.
Therefore, the molality is
m = [tex]\frac{10.5 mol NH3}{0.75558 kg solvent}[/tex] = 13.8966 m .

A gas mix consist of methane, argon , nitrogen, the total pressure of gas mixture is 81.89 kpa.
According to the Dalton's law of partial pressure.
The partial pressure of gas = the mole fraction of gas × total pressure.
Total pressure of gas = some of the partial of all the constituent gases.
no. of mole = mass of substance / mass of one mole
now,
The no. of moles of methane = ( 337 mg × 1 g ) / ( 1000 mg × 16 g/mol)
= 0.0210 g/mols
The no. of moles of argon = (148 / 1000 )g / 40 g/mol
= 0.0037 mols
The no. of moles of nitrogen = (210 / 1000 g) / 28 g/mol
= 0.0075 g/mols
The total no. of moles = 0.0210 + 0.0037 + 0.0075
= 0.0322 mols
The mole fraction of nitrogen = 19.0 kpa
therefore ,
The total pressure = partial pressure of a gas / mole fraction of the gas

After three shifts, the resulting structure does have separated charges, with a positive charge on one of the oxygen atoms (which is not too favorable, considering the oxygen's high electronegativity), but all the non-hydrogen atoms still have a full octet and the presence of the aromatic ring does greatly stabilize the structure. It also explains why the compound (resonance hybrid) is aromatic.
