Answer 2

800 mL of methyl alcohol should be added to 200 ml of water to make this solution.

Explanation:

Volume of the methyl alcohol = x

Volume of water = y = 200 mL

Volume of the solution ,V = x + y

Volume percentage of solution = 80%

$(v/v)\%=\frac{x}{x+y}\times 100$

$80\%=\frac{x}{x+200 mL}\times 100$

x = 800 mL

800 mL of methyl alcohol should be added to 200 ml of water to make this solution.
