Answer to Question #261710 in General Chemistry for lala

Question

1. The airbag is a safety device used in cars to cushion the passenger during a crash. It involves the following chemical reaction which is triggered by an impact: 2 NaN3 (s) g 2 Na (s) + 3 N2 (g) Calculate the volume of N2 gas (measured at STP) that can be produced from 130.0 g of NaN3 (molar mass = 65).

Answer 1

130/65= 2moles

Mole ratio NaN3:N2= 1:3

Molar mass of N2= 28.0134 g/mol

= 3×2×28.0134 g/mol

= 168.0804g
