Answer to Question 1

ANS: B
Percent solution. A percent solution is weight of solute per weight of solution. Five grams of glucose dissolved in 95 g of water is a true percent solution. The glucose is 5 of the total solu-tion weight of 100 g.

Answer to Question 2

ANS: D
It is defined as weight of solute per volume of solution. This method is sometimes erroneously described as a percent solution. W/V solutions are commonly expressed in grams of solute per 100 ml of solution. For example, 5 g of glucose dissolved in 100 ml of solution is properly called a 5 solution.
