POGIL-Stoichiometry How do chemists use balanced chemical equations? got bit D 23 mosquitoes? 10 He got Mol-aria Why? Chemists use balanced chemical equations as a basis to calculate how much reactant is needed or product is formed in a reaction. This is called Stoichiometry- (stoi-key-ah-meh-tree) Another way of looking at it is using the mole ratio from the balanced equation and information about one compound in the reaction to determine information about another compound in the equation. A mole ratio...

15. The Basic Problem In this section we will practice calculating the amounts of products produced in a chemical reaction using the three-step method. This method can be shortened later by combining the steps. 1 mole Step 1. Convert to moles: multiply grams by Tarla mass is grams Step 2. Use the chemical equation to relate the products to the reactants. Multiply the answer from Step 1 by the confident of the...
