When a teacher dilutes 50 mL of 2.0 M NaOH to 0.50 M, what volume of NaOH results?

= 200 mL

Explanation:

Using the dilution formula;

M1V1 = M2V2;

Where, M1 is the concentration before dilution, V2 is the volume before dilution, while M2 is the concentration after dilution and V2 is the volume after dilution.

M1 = 2.0 M

V1 = 50 mL

M2 = 0.50 M

V2 = ?

V2 = M1V1/M2

= (2.0 * 50) / 0.5

= 200 mL

Therefore, the volume after dilution will be, 200 mL
