Air-bags can be inflated by the decomposition of sodium azide, NaN3. At 25.0◦C and 1.10 atm, what volume of N2(g) is produced by
the decomposition of 71.4 g NaN3 under the following chemical reaction: 2NaN3(s) → 2Na(l) + 3N2(g)
1 answer:
Answer:
V = 36.7L of 
Explanation:
1. Write the chemical reaction for the decomposition of sodium azide:

2. Find the number of moles of
produced by the decomposition of 71.4g of
:

3. Use the ideal gas equation to find the Volume of
occupied by 1.65 moles of
, at the temperature and pressure given by the problem:

Solving for V:

Converting the temperature from ◦C to K:
25◦C+273.15=298.15K
Replacing values:

V=36.7L of
