Question

The gas having same number of molecules as $16g$ of oxygen is

• A. 16g. of O3
• B. 16g. of SO3
• C. 48g. of SO3
• D. 1gm of hydrogen

Answer 1

The correct option is D

1gm of hydrogen

No. of molecules = $\frac{W}{MW}\times N$

$16g$ of oxygen contains $\frac{N}{2}$ molecules

$1g$ of hydrogen also contains $\frac{N}{2}$ molecules.
