What is the molarity of a HNO₃ solution prepared by adding 255.4 mL of water to 350.0 mL of 12.3 M HNO₃? A)16.9 M B)7.45 M C)7.11 M D)2.61 M E)3.14 M

Question

Quizplus · Accepted Answer

Using the equation M1V1 = M2V2, where M1 and V1 are the initial concentration and volume, and M2 and V2 are the final concentration and volume, we can solve for the final concentration:

M1V1 = M2V2
(12.3 M)(350.0 mL) = M2(350.0 mL + 255.4 mL)
M2 = (12.3 M x 350.0 mL) / (350.0 mL + 255.4 mL)
M2 = 7.11 M

Therefore, the molarity of the final solution is 7.11 M.
