Unit 3: Conservation of Matter & Stoichiometry

  1. You calculate that you will get 300.0 g of sodium chloride using stoichiometry, but you actually get 213.0 g of sodium chloride. What is the percent yield?
  2. When synthesizing excess sodium and 100.0 g of chlorine gas in the lab you produce 40.0 g of sodium chloride. What is the percent yield?
  3. Given the equation: NaHCO3 + HCl ? NaCl + H2O + CO2 Assume that you start with 2.00 g of sodium bicarbonate and excess hydrochloric acid and you end up with 10.0 g of sodium chloride, what is your percent yield in this reaction?
