Method

  1. Calculate the mass of salt using mass of salt water in beaker - mass of water in beaker
  2. Finally Repeat the experiment using different temperatures of water.
  3. Add potassium chloride until no more will dissolve
  4. Measure the mass of the salt solution with a mass balance
  5. Measure the mass of the water and beaker with a mass balance
  6. Measure the temperature of the water with a thermometer
  7. First Measure 100 cm3 of water using a measuring cylinder
  8. Add the water to the beaker
