Question

Calculate the Molecular Mass of $\mathrm{Carbon}\mathrm{Dioxide}$ $\left({\mathrm{CO}}_2\right)$.

Answer 1

The Atomic mass of $\mathrm{Carbon}\left(\mathrm{C}\right)$ is $12$

The Atomic mass of $\mathrm{Oxygen}\left(\mathrm{O}\right)$ is $16$.

Therefore, Molecular Mass of $\mathrm{Carbon}\mathrm{Dioxide}$ $\left({\mathrm{CO}}_2\right)$ = Atomic mass of $\mathrm{Carbon}$ $+$ $2\times$(Atomic mass of $\mathrm{Oxygen}$).

Molecular Mass of $\mathrm{Carbon}\mathrm{Dioxide}$ $\left({\mathrm{CO}}_2\right)$ = $12+2\times \left(16\right)$ .

= $44$g/mol

Hence, the Molecular Mass of $\mathrm{Carbon}\mathrm{Dioxide}$ $\left({\mathrm{CO}}_2\right)$ is $44$g/mol.
