How many grams of sodium azide are required to form 16.55g of nitrogen gas in

MrRissso [65]

Answer:

16.8128 grams of sodium azide is needed

Explanation:

2NaN3 = 2Na + 3N2

molar mass of NaN3 =

$2(11 + (7 \times 3) = 64$

molar mass of N2

$3(7 \times 2) = 42$

moles of N2 =

moles=mass/R.F.M

16.55÷42 = 0.3940

mole ratio=

2NaN3 : 3N2

3 = 0.3940

2=?

$0.394. \times 2 \div 3 = 0.2627$

Mass of sodium azide =64×0.2627

=16.8126
