Calculate the mass of nitrogen that would be produced when 130 g of sodium azide decomposes?
The mixture of chemicals contains sodium azide (NaN3) which decomposes on heating to form sodium and nitrogen.
2NaN3 -> 2Na + 3N2
Relative atomic masses (Ar): N = 14; Na = 23
Could someone explain how to work out the answer please step by step.
much appreciated.
Nitrogen’s atomic mass is 14.01 g/mol. But a nitrogen gas’s atomic mass is 28.02 g/mol because it is diatomic. Take note that there is a difference between Nitrogen (N) and Nitrogen gas (N2). In this video well learn to convert moles of N2 to grams. The technique used can be applied to any mole to gram conversion. For our practice problem we’ll co.

Atomic Mass Of N2hpo4
-grams NaN3 to moles NaN3 to moles N2 to grams N2
To go from grams NaN3 to moles NaN3 you must know the molar mass of NaN3.
molar mass NaN3 = 23.0 g + 3(14.0 g) = 66.0 g/mole
molar mass N2 = 2(14.0 g) = 28.0 g/mole
1st, calculate moles NaN3 = 130 g NaN3(1 mole NaN3)/(66.0 g NaN3) = 1.969 mole NaN3
2nd, calculate moles N2 produced = 1.969 mole NaN3(3 moles N2)/(2 moles NaN3) = 2.954 mole N2
3rd, calculate mass N2 produced = 2.954 mole N2(28.0 g N2)/(1 mole N2) = 82.7 g N2
Hope this is helpful to you. JIL HIR

Given, m(NaN3) = 130g
Molar mass of NaN3 = 23+(14*3) = 65 g/mol
As, n = m/M
n(NaN3) = 130/65 = 2mol
Now, working the number of moles of Nitrogen (N2)
n(N2) = (3/2)*n(NaN3) = (3/2)*2 = 3mol
m(N2) = n*M = 3*(14*2) = 84g
