A car airbag is inflated by N ₂ produced during rapid decomposition of NaN ₃(s) . What will be the pressure of the inflated airbag if 130 ~g of NaN ₃ is used. The volume of airbag is 10 ~L (T=300 ~K , R=0.082 ~L ~atm ~K ⁻¹ ~mol ⁻¹ )

Step-by-step solution

Given that, 2 NaN ₃ 2 Na +3 ~N ₂ Number of moles of sodium azide = 130 65 =2 Number of moles of nitrogen =2 3 2 =3 We know that, V= n R T p 10= 3 0.0821 300 p aligned p & = 3 0.0821 300 10 =7.389 ~atm & 7.38 ~atm aligned
