Igcse Model Questions Vol1 2022 Chemistry Question 37
Practice objective / multiple choice question 37 from the 2022 Igcse Model Questions Vol1 Chemistry examination.
At 25 °C the solubility of sodium chloride in water is 35.7 g per 100 g water, and at 35 °C it is 45.2 g per 100 g water. Assuming the enthalpy of solution is constant over this temperature range, calculate the enthalpy change \(\Delta H_{\text{sol}}\) (in kJ mol\(^{-1}\)) for the dissolution of NaCl. The molar mass of NaCl is 58.44 g mol\(^{-1}\). Give your answer to the nearest whole kJ mol\(^{-1}\).
