In solid-liquid solutions, volume of solution is larger than the volume of solvent.

• True

• False

In liquid-liquid solutions, volume of solution can be larger than volumes of sum of solute and solvent.

• True

• False

To calculate the concentration of a solution, multiply the mass of the solute (grams) with the volume of solvent (mL).

• True

• False

If 3.0 g of sugar is mixed in water to make 30 mL of solution, its concentration is:

• 0.1 g/mL

• 0.1 %

• 0.1 mL/g

• 1.0%

Suppose that a solution was prepared by dissolving 18.0 g of sugar into 100g of water. The percent by mass in the nearest whole number would be calculated as follows:

• 15%

• 18%

• 6%

• 82%

If a solution is made by taking 70 mL of ethanol and adding enough water to make 750 mL of solution, the percent volume is:

• 9.3%

• 10.7%

• 0.09%

• 70%
