Method

  1. Add the water to the beaker

  2. Calculate the mass of salt using mass of salt water in beaker - mass of water in beaker

  3. Measure the temperature of the water with a thermometer

  4. Add potassium chloride until no more will dissolve

  5. First Measure 100 cm3 of water using a measuring cylinder

  6. Measure the mass of the salt solution with a mass balance

  7. Finally Repeat the experiment using different temperatures of water.

  8. Measure the mass of the water and beaker with a mass balance
