Solving <strong>Stoichiometry</strong> Problems • For chemical problems: • g of Known Substance ÷ mass of 1 mole = moles of Known Substance • Use moles of Known Substance and ratio from equation to get moles of Unknown Substance. • Moles Unknown Substance x mass of 1 mole = g of Substance 2.
Examples • Let’s try a couple of full-blown stoichiometry problems, but we will start simple. • CH 4 + O 2 CO 2 + H 2 O • First, balance the equation. • CH 4 + 2 O 2 CO 2 + 2 H 2 O • What is the mole ratio of the reactants and products? • 1:2:1:2
