Measuring Mass using Evaporation

Measuring Mass using Evaporation

1. 1) Measure the mass of the empty container

2. 2) Measure the mass of the container and the solution

3. 3) Heat the solution to evaporate the solvent

4. 4) Measure the mass of the container and the remaining solute

5. 5) Gently reheat to make sure all the solvent has been evaporated

6. 6) Measure the mass of the container and the solute again

7. If there is no further difference in the masses, the mass of solute dissolved in the solvent has been determined. The mass of solvent used has also been determined
