$\huge \bold \color{yellow}{♡Answer♡}$

➭Volume of Solution= 500mL

Volume by Volume percentage= 70%

Volume Percentage=

$\frac{volume \: of \: solute}{volume \: of \: solution} \times 100$

Now take 350mL of alcohol in 500mL measuring flask. Add water to it till it's volume becomes 500mL. Mix the contents thoroughly to get the 70% Solution.
