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(s) + H2CO3(aq) Ca(HCO3)2(aq)

What mass of limestone must have dissolved if 1.98 1010 kg of calcium hydrogen carbonate was produced?
