Answer: V1 = 45.6 ml

Explanation:

This is a dilution process whereby the concentration of phosphate in the solution is being reduced from 4.5m to 2m. Meanwhile. In a concentration process, the concentration of the phosphate solution will be increased. It can be achieved by removing solvents.

The dilution equation will be used. The equation is as follows:

M1V1 = M2V2 where

V1 = Initial volume of phosphate solution.

M1 = Initial concentration of phosphate solution.

V2 =Final volume of phosphate solution.

M2 = Final concentration of phosphate solution .

From the information given,

M1 = 4.5

V1 = ?

M2 = 2.0

V2 = 80

4.5 × V1 = 2×80

4.5V1 = 160

V1 = 160/4.5

= 35.6 ml

Oil molecules like to stick to other oil molecules more than they like to stick to water molecules. This is because mineral oil has nonpolar molecules and water has polar ones.
