Beaker, Water (Solvent), Triple Beam Balance, Sugar (solute), Blue Food Coloring (to see more easily), spoon (for mixing).
Procedure:
1. Weigh empty beaker.
2. Fill with water.
3. Weigh some sugar cubes.
4. Find the weight of the beaker with water.
5. Add the sugar cubes and stir.
6. Obtain a total weight.
7. Determine the weight of the solution only...you must subtract the mass of the empty beaker.
Results:
Beaker A (empty)
Beaker A Empty Mass = 220.2 grams
Beaker A Mass with Water= 417.5 grams
Mass of Sugar Cubes = 36.4 grams
Mass of Sugar and Water Solution= 453.9 grams
Conclusion
A solution is made up of solute and solvent. The total mass of a solution is equal to the mass of the solute plus the mass of the solvent. If you have two of the three numbers, you can find the third number mathematically.
