At the design bench of a crash test hall, weigh sodium azide (NaN₃) and count it in moles, find the moles of nitrogen from the coefficients of 2NaN₃ → 2Na + 3N₂, and get the airbag's volume and pressure from the ideal gas law. After watching an inflated bag's volume follow absolute temperature in a climate chamber, find the mass that catches the dummy safely in a crash test.
