**Problem Statement:**Calculate the molar enthalpy for dissolving 25 g of NaCl in 100 g of water inside a calorimeter. The calorimeter heat capacity is 500 J/°C. The initial temperature is 25°C and the final temperature is 26.5°C.**Explanation:**To solve this problem, one must use the formula for heat transfer in a calorimeter:Q = (C_calorimeter + m_water * c_water) * ΔTWhere:- Q is the heat absorbed or released (in Joules).- C_calorimeter is the heat capacity of the calorimeter (500 J/°C).- m_water is the mass of the water (100 g).- c_water is the specific heat capacity of water (4.18 J/g°C, commonly used value).- ΔT is the change in temperature (final temperature - initial temperature).The molar enthalpy (ΔH) can be calculated by relating Q to the moles of NaCl dissolved:ΔH = -Q / nWhere n is the number of moles of NaCl. Calculate n using NaCl's molar mass (58.44 g/mol).
