A 5.0 g sample of an ionic compound (MW = 96.5 g/mol) is placed in 50.0 g of water at 25 °C and the solution is stirred. When the salt is completely dissolved, the temperature of the solution is 32.7 °C.(3pts)a. Is the heat of solution endothermic or exothermic?

An insulated calorimeter contains 100 g of water at 10 °C. A salt is added to the solution, causing the temperature to drop by 3 °C. Is the heat of solution for the salt endothermic or exothermic? Group of answer choicesexothermicendothermic

An insulated calorimeter contains 100 g of water at 10 °C. A salt is added to the solution, causing the temperature to drop by 3 °C. If twice as much salt were added the solution, assuming it all dissolved, what would be the final temperature of the solution? Group of answer choices7 °C4 °C0 °C10 °C

A certain ionic compound X has a solubility in water of 40.7gL at 20.°C. Calculate the greatest mass of X that could be dissolved in 8.0L of water at this temperature. You may assume the volume of the solution doesn't change as the X is dissolved.Be sure your answer has the correct unit symbol and 2 significant digits.
