Hi,

As the system is thermally insulated ,Heat given out by steam is heat absorbed by the system

Heat given out by steam during condensation=M540

Heat given out by water at100C to go to40C=MCpwater(10040)

Heat absorbed by ice during melting=20080

Heat absorbed by water at0Cto go to40C=200Cpwater(400)

Heat balance givens

M540+MCpwater60=20080+200Cpwater40

Cpwater=1cal/gmC.

M540+M60=20080+20040

M600=16000+8000

=24000

M=60024000

M=40gm
