- I am confused on how to find the enthalpy change with this information. Thank you!arrow_forwardA calorimeter contains 24.0 mL of water at 11.0 °C. When 2.20 g of X (a substance with a molar mass of 52.0 g/mol) is added, it dissolves via the reaction and the temperature of the solution increases to 25.0 °C. Calculate the enthalpy change, AH, for this reaction per mole of X. Assume that the specific heat of the resulting solution is equal to that of water [4.18 J/(g · °C)], that density of water is 1.00 g/mL, and that no heat is lost to the calorimeter itself, nor to the surroundings. Express the change in enthalpy in kilojoules per mole to three significant figures. ► View Available Hint(s) AH = X(s)+H2O(1)→X(aq) VE ΑΣΦ ? kJ/molarrow_forwardPlease answer both questionsarrow_forward
