Joules
2. What happens to the concentration of a solution when you add more solvent?
It increases
It decreases
It remains the same
It depends on the solute
3. A solution with a high concentration of solute is described as a solution.
4. The formula for calculating molarity is moles of solute divided by of solution.
5. Explain the difference between a saturated and an unsaturated solution.
6. A chemist prepares a solution by dissolving 25.0 grams of sodium chloride (NaCl) in enough water to make a total volume of 500.0 mL. Calculate the molarity of the solution. (Molar mass of NaCl = 58.44 g/mol)
