Answer:
The molar mass of CaCO3 is 100.0869 g/mol. We need to add the molar masses of calcium (40.078 g/mol), carbon (12.0107 g/mol) and three oxygen atoms...

Answer:
The molecular mass of calcium carbonate (CaCO₃) is 110
Explanation:
given,
mass of Ca-40,
mass of O-16,
mass of C-12,
mass of H-1,
mass of Na-23,
The molecular formula of calcium carbonate is CaCO₃.
Here, we require only mass of Ca, C, O elements.
The molecular mass of CaCO₃ is
CaCO₃ = 40+12+3(16)
⇒ CaCO₃ = 62+48
⇒ CaCO₃ = 110
∴ the molecular mass of CaCO₃ is 110
