A stock solution of HNO₃is prepared and found to contain 13.5 M of HNO₃. If 25.0 mL of the stock solution is diluted to a final volume of 0.500 L, the concentration of the diluted solution is M. A) 1.48 B) 0.270 C) 675 D) 0.675 E) 270

Question

Quizplus · Accepted Answer

We can use the formula:

M1V1 = M2V2

Where:

M1 = initial concentration
V1 = initial volume
M2 = final concentration
V2 = final volume

Plugging in the values we have:

M1 = 13.5 M
V1 = 25.0 mL = 0.025 L
M2 = ?
V2 = 0.500 L

M2 = (M1V1)/V2
M2 = (13.5 M x 0.025 L)/0.500 L
M2 = 0.675 M

Therefore, the concentration of the diluted solution is 0.675 M.

The correct answer is D.
