Correct option is C) Water in equilibrium with ice has a steady temperature of zero degree celcius Water in liquid state, has a specific heat of exactly 1 calorie per gram Molar mass of water is 15.999+2.016=18.015 grams per mole Therefore, the molar heat capacity of water at zero degree celcius =18.015×1 calorie/mol/k =18.015×1×4.184 J/mol/k =75.48 J/mol/k
