What is the concentration of HCl in the final solution when 65 mL of a 12 mol L^-1 HCl solution is diluted with pure water to a total volume of 0.15 L?

Question

Quizplus · Accepted Answer

Using the formula:

M1V1 = M2V2

Where,

M1 = 12 mol/L (concentration of HCl solution)
V1 = 65 mL (volume of HCl solution)
M2 = concentration of final solution
V2 = 150 mL (total volume of final solution)

Converting all units to L and substituting the values:

(12 mol/L)(65 mL/1000 mL) = M2(150 mL/1000 mL)

M2 = (12 mol/L)(65 mL/150 mL) = 5.2 mol/L

Therefore, the concentration of HCl in the final solution is 5.2 mol/L.

Option B is the correct answer.
