When a collision occurs, a sensor sends an electric signal to a canister containing sodium azide (NaN3). This generates heat, which starts the chemical reaction that produces nitrogen gas, which inflates the airbag. The chemical reaction is: K◄◄ 2NaN3(s)→ 2Na(s) + 3N₂(g) If a typical airbag contains 135 g of sodium azide, how many grams of nitrogen gas can be produced?
