How would you prepare 50.0 mL of 2.0 M H2SO4 starting with concentrated sulfuric acid (18M)?

1 answer

c1v1 = c2v2
c = concn
v = volume
50 x 2.0 = x*18
solve for x
Take x mL of 18 M H2SO4, transfer quantitatively to a 50 mL volumetric flask and add water (deionized or distilled of course) to the mark on the volumetric flask. Stopper and mix thoroughly.
