Question

An inflated airbag has a volume of 5.00x10^4 cm^3 at STP. The density of N2 (g) at STP is .00125 g/cm^3. What is the total number of grams of N2 (g) in the airbag?

Answer 1

The total number of grams of nitrogen is known after multiplying the volume of airbag by the nitrogen density.
m = 5,00х10^4x0,00125 = 62,5 g N2
