If I add water to 100mL of a 0.15 M NaOH solution until the final volume is 150mL, what will the molarity of the diluted solution be?

The molarity of the diluted solution be 0.10 M

Explanation:

According to the dilution law,

where,

= concentration of concentrated solution = 0.15 M

= volume of concentrated solution = 100 ml

= concentration of diluted solution= ?

= volume of diluted solution= 150 ml

Putting the values we get:

Thus the molarity of the diluted solution be 0.10 M
