Question

. a sample of milliolite limestone obtained from porbandar gujarat is found to contain 54.5% cao (by weight). if this cao is present as caco3 in the limestone find the content of caco3 in the limestone

Answer 1

"Answer

Let's just calculate the mass ratio of CaCO3 to that of CaO.

Atomic weights are following:

Calcium 40.08,

Carbon 12.00,

Oxygen 16.00.

Molar mass of CaO = 56.08

Molar mass of CaCO3 = 100.08

Then 54.5% times (100.08/56.08) = 97.26%

Therefore, the content of caco3 in the limestone is 97.26% by mass.
