A10 m concentrated stock solution of nacl was used to prepare 5 liters of diluted 1 m solution. which of the following statements is true about the process used to achieve this required dilution?

a. the volume of stock solution used was less than 0.4 liters.
b. the volume of stock solution used was more than 5 liters.
c. the volume of the solvent used was less than 0.4 liters.
d. the volume of the solvent used was less than 5 liters.

D. The volume of the solvent used was less than 5 liters.

Explanation:

(MV) before dilution = (MV) after dilution.

M before dilution = 10.0 M, V before dilution = V of stock = ??? L.

M after dilution = 1.0 M, V after dilution = 5.0 L.

V before dilution = V of stock = (MV) after dilution/M before dilution = (1.0 M)(5.0 L)/(10.0 M) = 0.5 L.

∴ The volume of the stock used is 0.5 L.

The volume of the solvent used is 4.5 L.

D. The volume of the solvent used was less than 5 liters.

D. The volume of the solvent used was less than 5 liters.
