Step 1 Introduction
Enthalpy change is equal to the amount of heat supplied to a substance at constant pressure. The change in standard molar enthalpy during the process of change in physical state of a substance is known as the Standard Enthalpy of transition. The given problem is based on the Standard enthalpy of fusion(conversion of ice to water). Standard enthalpy of fusion is also known as latent heat of fusion.
Heat required (Q)= mass of the substance(m) x latent heat of fusion of water(Lf).
Mass of the given ice = 349.4 g
