Mass of Nitrogen= 42 grams
Given
one mole of Sodium azide
Required
mass of Nitrogen
Solution
Reaction
The decomposition of one mol of sodium azide :
2 N a N 3 ( s ) → 2Na ( s ) + 3 N2 ( g )
From the equation, the mol ratio of N a N 3 ( s ) : N2 ( g ) = 2 : 3, so mol N2 :
= 3/2 x mol N a N 3
= 3/2 x 1
= 1.5 moles
Mass of Nitrogen
= mol x molar mass
= 1.5 x 28 g/mol
= 42 grams
