Let the density of the liquid in the density bottle be `d`
 Then volume of the liquid at 34degree centigrade V1=md=104.5d
 volume of the liquid expelled when it is heated to 100degree centigrade(V2-V1)=4.5d
 Coefficient of apparent expansion of liquid=[V2-V1]/[V1*(100-34)]
                                                                             =[4.5d]/[104.5d*66]

							let the density of the liquid in the density bottle be d.
given that mass of liquid m1=104.5gms
                                        t1=34
                                        m2=m1+4.                                       
                                             =104.5+4.5
                                              =109gms
we know that coefficient of apparent expansion =(V2-V1)/V1*(t2-t1)
