I need help with a chemistry question...please help me.?
so here is the question...
when surface water dissolves carbon dioxide, carbonic acid (H2CO3) is formed. When the water moves underground through limestone formations, the limestone dissolves and caves are sometimes produced.
CaCO3+H2CO3==>Ca(HCO3)2
what mass of limestone must have dissolved if 3.05 x 10^10kg of calcium hydrogen carbonate was produced?

CaCO3 + H2CO3 ------> Ca(HCO3)2
M= 3.05*10^13 g
Mass of limestone dissolved
= (3.05*10^13g) * 1mol/ 162.12g *1mol/1mol * 100.09g/1mol=1.88e13 g
