When sensors in a car detect a collision, they cause the reaction of sodium azide, NaNg, which generates nitrogen gas to fill

science chemistry

Answer 1

Answer #1

Molar mass of NaN3 = 65g/mol

Moles present = mass / molar mass = 142/65 = 2.184 moles

According to reaction 2 moles NaN3 produces 3 moles N2

So, 2.184 moles will produce (3/2) x 2.184 = 3.276 moles

One mole at STP equals 22.4 liters

So volume of N2 will be = 22.4 x 3.276 = 73.38 L
