The air consists of 79.2 % of Nitrogen, 20.7 % of Oxygen, 0.08% of other light gases and the remaining gas is Argon. The volume of air consisting one cubic metre of Argon

Answer :

Let Volume of air consisting one cubic meter of Argon  =  x  .

And Percentage of Argon in air  =  100 - ( 79.2 + 20.7+ 0.08 ) =  100 - 99.98  =   0. 02%  , So

0.02% of x  =  1 cubic meter ,

0.02x100 =  1 cubic m x5000 =  1 cubic m x =  5000 cubic m 
So,
Volume of air consisting one cubic meter of Argon  = 5000 cubic meter                                               ( Ans )
