Examples • Next, calculate the molar masses of each material. • CH 4 = 16.0 g/mol • O 2 = 32.0 g/mol • CO 2 = 44.0 g/mol • H 2 O = 18.0 g/mol
Examples • If we start with 50.0grams of methane, how many grams of oxygen will be required? These problems are as easy as 1, 2, 3. • 1. Convert grams methane to moles. • 50.0g x (1 mol CH 4 /16.0g) = 3.12 mol CH 4 • 2. Convert mol of methane to mol of oxygen. • 3.12 mol CH 4 x (2 mol O 2 /1 mol CH 4 ) = 6.24 mol O 2 • 3. Convert mol O 2 to grams. • 6.24 mol O 2 x (32.0g O 2 /mol) = 200. g O 2
