The balanced chemical reaction is given as:
Now, convert into litres.
So,
Density is equal to the ratio of mass to the volume.
where, M = mass and V= volume
Substitute the value of density and volume in formula to get the value of mass.
Now, number of moles of gas=
=
According to the reaction, 2 moles of sodium azide gives 3 moles of nitrogen gas.
Now, in 24.00 moles of nitrogen gas produced from= of nitrogen gas, moles of sodium azide.
number of moles of sodium azide =
Mass of sodium azide in g = .
=
=
Thus, mass of sodium azide which is required to produce of nitrogen gas =
