Solution

The correct option is D 96 g
According to the law of constant proportions, the elements of a chemical compound are always combined together in a fixed proportion.

In a ${CO}_{2}$ molecule, the ratio of the mass of oxygen to that of carbon atoms is given below.

$\frac{A t o m i c m a s s o f o x y g e n}{A t o m i c m a s s o f c a r b o n} =$ $\frac{32}{12}$

So, if total mass of $C O_{2}$ is given to be 36 g, then the mass of oxygen in the sample = $\frac{32}{12} \times$ 36 = 96 g
