Marble is composed of mostly calcium carbonate.?

Question

Assuming that acid rain contains 4.00×10^−5 M H2So4 , approximately what volume of rain is necessary to dissolve a 230 marble statue?

Answer 1

Atomic weights: Ca=40 C=12 O=16 CaCO3=100

Let marble be called M.

230lbM x 1000gM/2.2lbM x 1molM/100gM x 1molH2SO4/1molM x 1LH2SO4/4.00x10^-5molH2SO4 = 2.61 x 10^7 L rain.
