    3. Atomic weight of Ru = 101.072 grams per mole
      1. 1.01 grams of Ru = 0.009992876 moles
    4. Six moles of NaCN.2KCN are needed
      1. Average molar mass of NaCN.2KCN = 59.75 grams per mole
      2. Mass of NaCN.2KCN needed = 3.58 grams

      1. After dissolving in water a small amount of an unknown white precipitate was left over. 
      2. Lead Nitrate molar mass = 331.2 grams per mole
      3. 25 grams (to account for the mystery precipitate) of lead nitrate = 0.0754831 moles/span>
      4. Molar mass of sodium chloride = 58.443 grams per mole
      5. NaCl needed = 0.15096618 moles = 8.83 grams NaCl
    2. Lead chloride filtered, rinsed several times with room temp water to remove as much sodium nitrate as possible and put into the desiccator to dry overnight. 
      1. 3/2/21: Mass of slightly damp PbCl2 = 212.34 - 196.82 = 15.52 grams of lead(II) chloride
