Stoichiometry mass and amount relationships between reactants and products in a chemical reaction Rules for Solving Stoichiometry Problems A balanced, properly written equation is essential because the coefficients tell you the mole to mole ratio. Converting to moles is essential! Example: When CaC2 reacts with water, acetylene gas (C2H2) and calcium hydroxide are produced. How many grams of water are required to produce 1.55 moles of C2H2? Step 1: Write a balanced equation. CaC2 + 2H2O ? C2H2 + Ca(OH)2 Step 2: Determine what info you have and what you are trying to determine. You know you need to produce 1.55 moles of C2H2, and you need to determine how many grams of water are required to do this.
