Question

vapour density of oxygen gas​

Answer 1

molar mass of O

2

gas = 32 g/mol.

Density = mass/volume.

=( 32g/mol) / (22.4 L/mol)

= 1.428 g/l.

Answer 2

Answer:

We all know that vapour density of a gas = molar mass of the gas/ molar mass of hydrogen gas of same volume.

The molar mass of Oxygen is about 15.9994 ~ 16

and molar mass of hydrogen gas is 2.016 ~ 2. Then vapour density of oxygen = 16/2 = 8
