Question

A gas occupies a volume of 45.8 liters at STP. How many molecules would be in

this volume of gas?

Answer 1

2.04 moles

Step-by-step explanation:

1 liter = 1
`dm^(3)`

and at S.T.P (standard temperature and pressure) one mole of any gas occupies 22.414
`dm^(3)`

setting up mole and volume ratio

moles : volume

1 : 22.414

X : 45.8

X = 45.8/22.414

X = 2.04 moles
