Gaseous methane (CH4) reacts with gaseous oxygen gas (O2) to produce gaseous carbon dioxide (CO2) and gaseous water (H2O). What is the theoretical yield of water formed from the reaction of 0.96g of methane and 3.3g of oxygen gas?

What are the options for above question if my answer is wrong?

Gaseous methane CH4 reacts with gaseous oxygen gas O2 to produce gaseous carbon dioxide CO2 and gaseous water H2O . If 9.56g of water is produced from the reaction of 7.38g of methane and 21.5g of oxygen gas, calculate the percent yield of water. Round your answer to 3 significant figures.

Liquid octane CH3CH26CH3 reacts with gaseous oxygen gas O2 to produce gaseous carbon dioxide CO2 and gaseous water H2O . What is the theoretical yield of water formed from the reaction of 77.7g of octane and 92.5g of oxygen gas? Be sure your answer has the correct number of significant digits in it.
