What is the change in temperature when 3.00 grams of Sodium chloride is dissolved in 100 mL of water? 2236.64 x °C Enter an integer or decimal number, accurate to at least 2 decimal places [more] Given the change in the temperature from adding 3.00 grams of Sodium chloride to 100.00 mL of water, calculate the enthalpy of solution for Sodium chloride in units of kj/mol. 674 x kj/mol * The number is greater than 2% off the expected value

In the given question we have to calculate the change in temperature and then the enthalpy of the solution.To calculate the change in temperature we can use the expression for freezing point depression,where,i is Van't Hoff factor, for the given reaction Kf is the freezing point depression, m is the molality.The molality can be calculated as follows:(a) The following information is given in the question,Mass of water will be,The number of moles of sodium chloride can be calculated as follows:The molality of the solution can be calculated as follows:The change in temperature can be calculated as follows:(b) The enthalpy of the solution can be calculated as follows:where,To convert the enthalpy in kJ/mol we have to divide it by moles.(a) The change in temperature is 1.9oC.(b) The enthalpy of the solution is 0.468 kJ/mol.
