Calculate the relative molecular mass of carbon dioxide.

Open in App

Solution

Molecular formula of carbon dioxide $= C O_{2}$

The atomic mass of Carbon $= 12$
The atomic mass of Oxygen $= 16$

$= 1 \times$ atomic mass of carbon $+ 2 \times$ atomic mass of oxygen.
$= (1 \times 12) + (2 \times 16) = 44$

Hence the relative molecular mass of carbon dioxide $= 44$ .
