  1. Stoichiometry Mrs. Russotto

  2. Working a Stoichiometry Problem E) How many grams of K2O will be produced from 0.50 g of K? 4 K + 1O22 K2O 0.50 g K 1 mol K 2 mol K2O 94.20 g K2O = ?g K2O 4 mol K 1 mol K2O 39.10 g K 0.60 g K2O

  3. Try this with your partner… F) How many grams of O2 are needed to react with 2.4 grams of K? 4 K + 1O22 K2O 2.4 g K 1 mol K 1 mol O2 32.0 g O2 = ?g O2 4 mol K 1 mol O2 39.10 g K 0.49 g O2
