17.85 mL of 3.0 M stock solution of nitric acid is needed to make a 150 mL 0.357 M nitric acid.
The dilution of a stock solution can be solved by using the formula below, which indicates that the concentration of the solution changes but the number of moles of the solute remains the same.
(concentration of stock solution)(volume of stock solution) = (concentration of diluted solution)(volume of diluted solution)
Given:
(3.0 M)(volume of stock solution)=(0.357 M)(150 mL)
volume of stock solution = [(0.357 M)(150 mL)] / (3.0 M)
volume of stock solution = 17.85 mL
