A well lagged copper calorimeter of mass 120g contains 70g of water and 10g of ice both at 0 degrees Celsius. Dry steam at 100 degrees Celsius is passed in until the temperature of the mixture Is 40 degrees Celsius. Calculate the mass of steam condensed.
*specific latent heat of fusion of ice=3.2×10²J/g
*specific latent heat of vaporisation of steam=2.2×10³J/g
*specific heat capacity of copper=4.0×10(raised to power minus one)J/g/k
Specific heat capacity of water=4.2J/g/k
