Answer to Problem 15PP

The mass of N2 produced from the decomposition of 100.0 g of NaN3 is 28.85 g.

Explanation of Solution

The given reaction used to inflate automobile bags is:

2NaN3(s)  2Na(s) + 3N2(g)

The number of moles of NaN3 is calculated using formula:

Number of moles=MassMolar mass

The molar mass of NaN3 is 65.01 g/mol.

Putting the values:

nNaN3 = 100.0 g65.01 g/molnNaN3 = 1.54 mol

From the balanced chemical reaction, the mole ratio of NaN3 and N2 is 2:3 that means 2 moles of NaN3 produces 3 moles of N2, so the number of moles of N2 produced from 1.54 moles of NaN3 will be:

1.54 mol of NaN3 ×2 mol of N23 mol of NaN3 = 1.03 mol of N2

Now, the mass of N2 formed is calculated as:

The molar mass of N2 is 28.01 g/mol. So,

Number of moles of N2=Mass of N2Molar mass of N21.03 mol=Mass of N228.01 g/molMass of N2 = 1.03 mol×28.01 g/molMass of N2 = 28.85 g

Hence, the mass of N2 produced from the decomposition of 100.0 g of NaN3 is 28.85 g.
