To what volume should 244 mL of a 7.08 M solution of nitric acid be diluted to, to prepare a

10.60 M solution?

163 mL

Explanation:

Use the following equation

M1V1=M2V2

Plug in what you have and you get

(7.08 M) (244 mL) = (10.60 M) (V2)

Use algebra to solve for V2 by dividing both sides by 10.60 and you get the unknown volume which is 163 mL

Be careful of the units for volume. Notice I didn't bother to convert to Liters.
