Initial                                                                      Final

T1 = 20+273 = 293K                                           T2 = 89+273   = 362K

V1   =                                                                     V2 = 449ml

                 V1/T1     =        V2/T2

                  V1          =       V2T1/T2

                                   = 449*293/362

                                   = 363ml

The initial volume = 363ml >>>>answer
