Problem Example 9: fuel-to-oxygen mass ratio in combustion of methane. Calculate the mass ratio of CH 4 to O 2 required for complete combustion. Solution: This is just the ratio of the molar mass of CH 4 (16 g) to that of two moles of dioxygen (2 x 32 g) Thus (64 g) / (16 g) = 4/1 = 4.0. molecules or moles of participants (reactants and products) in a chemical reaction. To be valid, the equation must be balanced. For example, the following stoichiometric equation is not balanced: C2H5OH+O2 →CO2 +H2O • The following equation is balanced because the number of atoms is the same on both sides of the equation (C, H, and O):

4 NH3 +5 O2 = 4 NO + 6 H2O the ratio between NH3 and O2 is 4 : 5 moles O2 required = 4.5 x 5 /4 =5.6 because we have only 3.2 moles of O2 this is the limiting reactant the ratio between O2 and H2O is 5 : 6 moles H2O = 3.2 x 6 / 5 =3.8 Dividing each result by the lowest number of moles (which may be for either P or S) and finding the lowest whole-number ratio of P and S gives us the empirical formula. To obtain the molecular formula, we compare the molar mass of the empirical formula to that given for the molecular formula (444.56 g/mol).
