Answer to Question #249587 in General Chemistry for mas

Question

In the laboratory you dilute 5.27 mL of a concentrated 12.0 M nitric acid solution to a total volume of 50.0 mL. What is the concentration of the dilute solution?

______ M

Answer 1

C_M = n / V

n₁ (HNO₃) = n₂ (HNO₃)

n = C_M x V

C_M1 x V₁ = C_M2 x V₂

12 x 0.00527 = C_M2 x 0.0500

C_M2 = (12.0 x 0.00527) / 0.0500 = 1.3 M
