Question

22.4 l of a gas weights 70g at STP. Calculate the weight of the gas if it occupies a volume of 20 l at 27 degree celcius and 700mm of hg of pressure

Answer 1

Answer:

Explanation:

PV=nRT

R= 0.082

P=700/760= 0.921 atm

T=273+27 = 300

0.921*20 = n *0.082* 300

n= 0.748 moles

1 mole contains 70g

0.748 contains ......?

0.748*70/1 = 52.414

Answer 2

Answer:

the above answer is very correct
