stoichiometry

• 1 mole = 6.02 times 10^24 units (avogadros #)
• a sample of an element with a mass equal to that elements average atomic mass expressed in grams contains 1 mol of atoms
• stoichiometry: the process of using the mole rations in a chemical equation to calculate the relative mass of reactants and products involved in a chemical reaction
• mole ratios: tell the relative proportions of reactants and products in a balanced chemical equation

  • obtained by reading coefficients
  • use conversion factors to make this calculation
