Answer: 10 ml of 200 mM
is required and 30 ml of water is required.
Explanation:
According to the dilution law,
where,
= concentration of stock solution = 200mM
= volume of stock solution = ?
= concentration of resulting solution= 50mM
= volume of another acid solution= 40 ml

Thus 10 ml of 200 mM
is required and (40-10) ml = 30 ml of water is to be added to make 40 ml of 50mM
.
