Question

The number of atoms in Nitrogen$\left(N_2\right)$ is twice the number of Helium $\left(He\right)$ in the same volume at the same pressure and temperature.

• A. True
• B. False

Answer 1

The correct option is A True

• At same temperature and pressure, volume is directly proportional to number of moles.
• Here we can see Nitrogen$\left(N_2\right)$ is diatomic gas which means number of atoms are $2$ where as Helium $\left(He\right)$ is monoatomic gas which means the number of atoms are only $1$.

Therefore, the given statement is true.
