Given, V1 =2500 cm3
                   P1 =760mm [At S.T.P]

  It is said that Hydrogen is subjected to 2.5 times increase in pressure.
  Thus final pressure , P2 of the gas is = 2.5 x P1
                                                          = 2.5 x 760
                                                     P2  = 1900 mm

We have to find out V2  [final volume] which the gas occupies
From Boyle's Law, At constant temperature

                                         P1V1 = P2V2

​                                       Thus , V2  =    P1V1P2
                                           V2  =   2500×7601900
                                        
                                           V2 = 1000cm3
