Question

Calculate the molecular mass of CO₂.

Answer 1

1. Molecular mass is the sum of the masses of all the individual atoms present in a molecule or compound.
2. Carbon dioxide is an acidic gas which releases during respiration.
3. The chemical formula of Carbon dioxide is CO₂.
4. The atomic mass of Carbon C is 12 u.
5. The atomic mass of hydrogen H is 1 u.
6. $\mathrm{Molecular}\mathrm{mass}\mathrm{of}\mathrm{carbon}\mathrm{dioxide}\left({\mathrm{CO}}_2\right)=(\mathrm{Atomic}\mathrm{mass}\mathrm{of}\mathrm{carbon}\mathrm{C})+(\mathrm{Atomic}\mathrm{mass}\mathrm{of}\mathrm{Oxygen})\mathrm{x}2$

$=(12\mathrm{x}1)+(16\mathrm{x}2)$

$=44\mathrm{g}/\mathrm{mole}$

The molecular mass of carbon dioxide CO₂ is 44 g/mole.
