Question

A copper Calorimeter of mass 150g,was half-filled with water of mass 300g and a temperature of 0°C.5g of ice of mass 0°C was added to the content, later some quantity of steam was passed into the mixture and the temperature rose by 20°C. Calculate the quantity of steam added.

Answer 1

Where is your attempt to solve this problem?
Where have you listed:
specific heat of Cu
specific heat of water
heat of fusion of water
heat of vaporization of water
I assume the steam is at 100 deg C
