How many millilitres of a stock solution of 11.1 mol L^-1 HNO₃ would be needed to prepare 0.500 L of 0.500 mol L^-1 HNO₃?

Question

Quizplus · Accepted Answer

Using the formula C1V1=C2V2, where C1 and V1 are the concentration and volume of the stock solution and C2 and V2 are the concentration and volume of the diluted solution:
V1 = (C2V2)/C1 
V1 = (0.500 mol/L x 0.500 L) / 11.1 mol/L 
V1 = 0.0225 L or 22.5 mL (since 1 L = 1000 mL) 
Therefore, 22.5 mL of the stock solution would be needed.
