What is the molecular mass of carbon dioxide?

Open in App

Solution

The molecular formula of carbon dioxide is $C O_{2}$
The atomic mass of oxygen is 16 u
The atomic mass of carbon is 12 u
The molecular mass of $C O_{2}$ = 2 x [atomic mass of oxygen] + [atomic mass of carbon]
= (2 x 16 u) + 12 u
= 44 u
