To what volume should you dilute 20 mL of a 12 M #H_2SO_4# solution to obtain a 0.16 M #H_2SO_4# solution?

Answer:

#C_1V_1=C_2V_2#.

A final volume of #1.500*L# is required.

Explanation:

The product #C_1V_1# is by definition the number of moles of stuff, which is fixed according to the volume and the concentration of your starting material.

We started with #20*mL# of #12*mol*L^-1# #"sulfuric acid"#.

And thus #(20*mLxx12*cancel(mol*L^-1))/(0.16*cancel(mol*L^-1))=V_2=1500*mL#

PS When you do the dilution, do you add the acid to the water? Why?
