The heat liberated when `1.89 g` of benzoic acid is burnt in a bomb calorimeter at `25^(@)C` increases the temperture of `18.94 kg` of water by `0.632 ^(@)C`. If the specific heat of water at `25^(@)C` is `0.998 cal//g "deg"`, the value of the heat of combustion of benzoic acid is

The heat liberated when 1.89g of benzoic acid is burnt in a bomob calorimeter at 25^(@)C and it increases the temperature of 18.94 kg of water by 0.632^(@)C . If the specific heat of water at 25^(@)C is 0.998cal*g^(-1)*""^(@)C^(-1) , the value of the heat of combustion of benzoic acid is-

The specific heat capacity of water is ____ cal//g^(@)C
