Q: Suppose a helium gas cylinder survived the fire and had the pressure valve replaced. Now it reads 1557 mm Hg in the cylinder, and it contains 4 moles of helium gas. Later the cylinder is sent out for a refill with more helium gas, and it comes back with a pressure reading of 3114 mm Hg. How many moles of helium gas are there in the cylinder now?

When solving through a gas stoichiometry problem, you want to begin with PV=nRT if a grams is what you are ultimately solving for. b volume is what you are ultimately solving for. c temperature is what you are ultimately solving for. d pressure is what you are ultimately solving for.
The human body burns glucose (C6H12O6) for energy according to this chemical reaction: C6H12O6+6O2→ 6CO2+6H2O The products of the reaction are carbon dioxide CO2 and water H2O Interestingly, all of the carbon dioxide and much of the water exits the body through the lungs: on every breath, the average person exhales 500.mL of air, which is typically enriched to 4% CO2 and 5% water vapor by volume. In short, when a person loses weight by dieting, the weight that is lost actually departs his body as a gas, every time he exhales. Each kilogram of body fat lost requires exhaling about 2.9kg of carbon dioxide. Calculate how many breaths it takes an average person to "exhale" 0.50kg of fat. Round your answer to the nearest thousand. You'll need to know that the density of CO2 is 2.0 kg/m^3 .
A sample of methane gas at a pressure of 0.947 atm and a temperature of 29.0 °C, occupies a volume of 711 mL. If the gas is allowed to expand at constant temperature until its pressure is 0.504 atm, the volume of the gas sample will be | mL.
A cylinder is filled with 10.0 L of gas and a piston is put into it. The initial pressure of the gas is measured to be 161. kPa. The piston is now pulled up, expanding the gas, until the gas has a final volume of 61.0 L. Calculate the final pressure of the gas. Be sure your answer has the correct number of significant digits. piston olo cylinder gas Ar I| kPa
Please answer number 5. Here is the complete question #5. 5.) In a car engine, a 425 mL cylinder and piston system is filled with a mixture of 0.83 g and 0.37 g of octane and oxygen gas, respectively. Both gases are at a temperature of 28 °C. If the total gas mixture is compressed to a pressure of 5.2 atm before combustion, calculate the total volume of the gas mixture at this point in time.

Ammonium carbamate will decompose into ammonia and carbon dioxide gasas. A 780.7 g sample of ammonium carbamate was allowed to decompose at a certain elevated temperature on a 10.0 L sealed container. A 25.0 mL sample of the headspace gas (i.e. the gas above the solid) was removed, and 0.0545 g ammonia could be isolated from that sample. NH4(NH2CO2)(s) = 2NH3(g) + CO2(g). (a) what cncenteration of ammonia, in mol/L was present in the headspace gas? (b) How many moles of ammonium carbamate had evaporated? Assume that the container volume is in addition to the volume of the solid (0.57 L) and that you may neglect the change in the volume occupied by the solid due to decomposition. (c) Calculate Kc for the decomposition of ammonium carbamate under these conditions.
