You wish to make a 0.257 M nitric acid solution from a stock solution of 3.00 M nitric acid. How much concentrated acid must you add to obtain a total volume of 50.0 mL of the dilute solution? Submit Answer Retry Entire Group 9 more group attempts remaining

Answers

Let us consider initial concentration (M1= 3M), initial volume (to be determined), final concentration (M2 = 0.257M) and final volume (V2 = 50 mL).

We can use following equation for calculating initial volume

M1 x V1 = M2 x V2

Rearranging above equation for V1 we get,

V1 = (M2 x V2) / M1

= (0.257 M x 50 mL) / 3 M

= 4.28 mL

Therefore volume required will be 4.28 mL
