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?  

Round your answer to 2 significant figures

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

Blast furnaces extra pure iron from the iron(III) oxide in iron ore in a two step sequence. In the first step, carbon and oxygen react to form carbon monoxide:

2C(s)+O2(g)--->2CO(g)

In the second step, iron(III) oxide and carbon monoxide react to form iron and carbon dioxide:

Fe2O3(s)+3CO(g)--->2Fe(s)+3CO2(g)

Suppose the yield of the first step is 65.% and the yield of the second step is 94.%. Calculate the mass of oxygen required to make 6.0kg of iron.

Be sure your answer has a unit symbol, if needed, and is rounded to 2 significant digits.
