Carmen Martinez · Answer 1

Total mass of CaCO3 = 40 amu of Ca + 12amu of C + 16*3 amu of oxygen = 100amu of CaCO3

i. e 100 tonnes of CaCO3.

mass of CO2 = 12amu of C + 2 * 16amu of O = 44 amu of CO2

mass % of CO2 in CaCO3 = (44/100) * 100 = 44%

i. e

44% of 100 tonnes is CO2.

=44 tonnes of CO2.

therefore, 44% of CO2 is present in CaCO3.
