Answer :
62 gm is the molar mass of H2CO3 (carbonic acid) is a chemical compound made up of hydrogen, carbon, and oxygen (H2CO3). It is produced in minute quantities when water dissolves its anhydride.
Given - Atomic mass - C = 12, H = 1, O = 16
To calculate the molar mass of H2CO3
= 1 x 2 + 12 x 1 + 16 x 3
= 2 + 12 + 48
= 62 gm
The construction of caves and cave structures like stalactites and stalagmites is aided by carbonic acid. The biggest and most typical caves are made when limestone or dolomite is dissolved by water that has recently rained and is high in carbonic acid. Near the bedrock/soil boundary, the limestone that lies above is where the calcite in stalactites and stalagmites is found. A diluted solution of carbonic acid is created when rainwater seeps through the soil and absorbs carbon dioxide from the carbon dioxide-rich soil. This acidic water reacts with the calcite in the limestone bedrock as it reaches the soil's base, bringing part of it into solution.
