Question

Gaseous butane (CH3(CH2)2CH3) will react with gaseous oxygen (O2) to produce gaseous carbon dioxide (CO2) and gaseous water (H2O) . Suppose 2.9 g of butane is mixed with 4.68 g of oxygen. Calculate the maximum mass of water that could be produced by the chemical reaction. Be sure your answer has the correct number of significant digits.
