Explanation:
To find the density of nitrogen gas at STP which is standard temperature and pressure, certain parameters must be known.
The mass of the gas must be given or its volume.
Density of a substance is the mass per unit area;
Volume of gas at STP = number of moles x 22.4
Using the volume obtained here,
Density =
Then we can find the density.
The mass is very important.
