What is the volume (ml) of methanol used to make 355ml of a 32.0% v/v solution in water?

113.6 mL

Since; 32.0% v/v methanol = 32 mL methanol in 100 mL of solution

We get an equation;

Therefore, the volume of methanol in 355mL solution is 113.6mL

113.6 ml of methanol is used to make 355 ml of a 32.0 V/v solution in water.

Explanation:

A 32 V/v solution of methanol contains 32 ml of methanol in 100 ml of solution. So, volume of methanol needed to make 355 mL of a 32 V/v solution is

On solving,

x=113.6 ml
