Find the molecular mass of carbon dioxide (CO2) in a.m.u.
44

Open in App

Solution

The correct option is A 44

Molecular mass is the sum of atomic masses of all the atoms present in the molecule.

We know that atomic mass of carbon is 12 u and that of oxygen is 16 u.

Thus, molecular mass of carbon dioxide ( $C O_{2}$ ) = (atomic mass of C) + $2 \times$ (atomic mass of O) = (12 + 32) = 44 u.
