How do you express % v/v?

x g/100 mL
x mL/100 mL
x g/100 g
x mL/100 g

The correct answer is: x mL/100 mL

A) This option is incorrect because % v/v expresses the ratio of volume of solute to volume of solution, not weight. C) This option is incorrect because % v/v expresses the ratio of volume of solute to volume of solution, not weight. D) This option is incorrect because % v/v expresses the ratio of volume of solute to volume of solution, not weight. The correct way to express % v/v is by using x mL/100 mL, which indicates the volume of solute in mL per 100 mL of solution. This is the standard way to express concentration in percentage by volume. Therefore, all other options are incorrect because they pertain to weight or volume in grams instead of mL.
