ID: 1023673 • Letter: G
Question
Gaseous butane will react with gaseous oxygen to produce gaseous carbon dioxide and gaseous water. Suppose 0.581 g of butane is mixed with 3.3 g of oxygen. Calculate the maximum mass of water that could be produced by the chemical reaction. Round your answer to three significant digits.

2C4H10 + 9O2 ---------> 8CO2 + 10H2O
no of moles of butane = W/G.M.Wt = 0.581/58 = 0.01 moles
no of moles of O2 = W/G.M.Wt = 3.3/32 = 0.103 moles
2 moles of C4H10 react with 9 moles of O2
0.01 moles of C4H10 react with = 9*0.01/2 = 0.045 moles of O2
limiting reagent is C4H10
2 moles of C4H10 react with O2 to form 10 moles of H2O
0.01 moles of C4H10 react with O2 to form =10*0.01/2 = 0.05 moles of H2O
mass of H2O = no of moles * gram molar mass of H2O
= 0.05*18 = 0.9g of H2O
0.900 of H2O
