A 4.21 g sample of an unknown salt (MM 116.82 g/mol) is dissolved in 150.00 g water in a coffee cup calorimeter Before placing the sample in the water, the temperature of the salt and water is 23.72 °C. After the sall has completely dissolved, the temperature of the solution is 28.54 °C What is the total mass inside the calorimeter in grams? What is the change in temperature, in "C, inside the calorimeter> Was the dissolution process endothermic or exothermic? What quantity of heat, in J, was gained by the solution? Assume the specific heat of the solution is the same as water, 4.184 Jig" °C. What is the total heat for the dissolution reaction of the 4.21 g of salt? What quantity in moles of the unknown salt were used in the reaction? What is the enthalpy change (in kJ/mol of salt) for the dissolution reaction? > A 4.21 g sample of an unknown salt (MM 116.82 g/mol) is dissolved in 150.00 g water in a coffee cup calorimeter Before placing the sample in the water, the temperature of the salt and water is 23.72 °C.
