# What is the atomic mass of calcium carbonate?

Jul 4, 2017

The formula mass of $\text{calcium carbonate}$ is the sum of the individual ATOMIC masses.......
And thus, for the formula mass of $\text{calcium carbonate}$, we take..
${\underbrace{40.08}}_{\text{Ca}} \cdot g \cdot m o {l}^{-} 1$ $+$ ${\underbrace{12.01}}_{\text{C}} \cdot g \cdot m o {l}^{-} 1$ $+$ ${\underbrace{3 \times 16.00}}_{\text{O}} \cdot g \cdot m o {l}^{-} 1$
$\cong 100 \cdot g \cdot m o {l}^{-} 1$
