Question

If I add water to 100Ml of a 0.75 m NaOH solution until the final volume is 165 ml , what will the molarity of the diluted solution be?

Answer 1

Answer:

0.45M

Explanation:

The following were obtained from the question:

C1 = 0.75M

V1 = 100mL

V2 = 165mL

C2 =?

Applying the dilution formula C1V1 = C2V2, the concentration of the diluted solution can be calculated for as follows:

0.75 x 100 = C2 x 165

Divide both side by 165

C2 = (0.75 x 100) /165

C2 = 0.45M

The concentration of the diluted solution is 0.45M
