The mass, specific heat capacity and the...

The mass, specific heat capacity and the temperature of a solid are `1000g,(1)/(2) cal/g - .^(@)C` and `80^(@)C` respectively. The mass of the liquid and the calorimeter are `900g` and `200g`. Initially,both are at room temperature `20^(@)C` Both calorimeter and the solid are made of same material. In the steady state, temperature of mixture is `40^(@)C`, then specific heat capacity of the unknown liquid.
