Solution

Calculating the mass of one mole of nitrogen gas:

Given,

Atomic weight of Nitrogen is given as = 14.0gmol-1

The mass of one mole of nitrogen gas,(N2) which is also known as the molecular weight, will be calculated as;

=14.0gmol-1×2=28gmol-1

Therefore, the mass of one mole of nitrogen gas, (N2) is calculated to be 28gmol-1
