heat energy lost by one body = heat energy gain by other body

so

Q1=Q2

Q= mc(T2-T2)

now the mass ot the copper block m= (mc delta T)water/(c* delta T) coppet

                                                           = 0.8*4190*11.8/385*183.7

                                                         =5.49 Kg
