Question

How many liters of N2 gas at STP are in a deployed car airbag whose N2 gas masses at 43.8 g?

PLEASE HELP

Answer 1

490.87 L

Step-by-step explanation:

Molar mass of N2 = (1 x 2) = 2 g

Moles of N2 in the airbag = 43.8/2 = 21.9 moles

One mole of any gas occupies a volume of 22.414 L at S.T.P

setting up ratio between moles and volume;

moles : volume

1 : 22.414

21.9 : X

X = (21.9 x 22.414)

= 490.87 L
