  1. Solution Concentrations II CHEM 210

  2. Convert %w/w to %w/v

  3. 100 mL of solution is a smaller amount than 100 g of solution Convert %w/w to %w/v

  4. 3.6 g ethanol x mL ethanol = 100 g solution 100 mL solution Convert %w/w to %v/v

  5. Ethanol is lighter than water, so a given amount by weight will occupy more volume Convert %w/w to %v/v

  6. Make Up a Dilute Solution • Need 100 mL of a 5.00 ppm solution of Fe • The solid is (NH4)2Fe(SO4)2·6H2O • Formula weights: • Fe 55.847 g/mol • (NH4)2Fe(SO4)2·6H2O 392.143 g/mol • How much (NH4)2Fe(SO4)2·6H2O is needed?
