Answer 2

Dear Student,

● Answer -

Atomic weight = 7 u

◆ Explanation -

# Given -

Vapour density = 14

Gas is diatomic

# Solution -

As the gas is diatomic, its relative mass will be -

Relative mass of atom = 2 × atomic weight

Vapour density of a gas is equal to its relative mass.

Vapour density = Relative mass of atom

Vapour density = 2 × atomic weight

Rearranging for atomic weight,

Atomic weight = vapour density / 2

Atomic weight = 14 / 2

Atomic weight = 7 u

Hence, atomic weight of the gas is 7 u.

Thanks dear. Hope this helps you...
