Answer:

113.6 mL

Explanation:

  • A 32.0% V/v methanol solution means 32.0 mL of methanol in 100 mL of solution.
  • Therefore, we can calculate the volume of methanol in 355 mL solution.

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

We get an equation;

[tex]\frac{32mL}{100mL} =\frac{x}{355mL}[/tex]

[tex]x =\frac{(355)(32)}{100}[/tex]

[tex]x=113.6mL[/tex]

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

Answer:

113.6 ml of methanol is used to make 355 ml of a 32.0[tex]\%[/tex] V/v solution in water.

Explanation:

A 32[tex]\%[/tex] 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[tex]\%[/tex] V/v solution is

[tex]\frac{32}{100}=\frac{x}{355}[/tex]

On solving,

[tex]\Rightarrow x= \frac{32\times355}{100}[/tex]

[tex]\therefore[/tex] x=113.6 ml
