Question

If 2ml of acetone is present in 45ml of its aqueous solution, calculate the concentration of solution.

Answer 1

Hello!

If 2 ml of acetone is present in 45 ml of its aqueous solution. Calculate the concentration of this solution.

We have the following information:

%V/V (percentage of volume per volume) = ?

V1 (solute volume) = 2 mL

V (volume of the solution) = 45 mL

We apply the data to the formula of volume percentage of the solute per volume of solution, we will have:

$\%\:v/v = \dfrac{v_1\:(ml)}{v\:(ml)} *100$

$\%\:v/v = \dfrac{2}{45} *100$

$\%\:v/v = \dfrac{200}{45}$

$\boxed{\boxed{\%\:v/v \approx 4.44}}\:\:\:\:\:\:\bf\green{\checkmark}$

Answer:

The concentration this solution is approximately 4.44%
