Agas that exerts a pressure of 6.20 atm in a container with a volume of will exert a pressure of 9.150atm when transferred to a container with a volume of 322ml

 a  gas   exert  a  pressure  of 6.20   atm  in a container  with a volume  of 475.2  ml  will  exert  a  pressure of 9.150  atm  when transferred   to a  container  with a volume  of 322 ml

     Explanation
This is  calculated  using the  Boyles  law   formula
that is P1V1= P2V2
P1=6.20 atm
V1=?
P2=9.150 atm
V2=  322  ml

by  making  V1  the subject of the   formula

V1= P2V2/P1

V2  is therefore =  (9.150 atm  x322 ml) / (6.20   atm-)  = 475.2  ml
