Work out problems: You must SHOW ALL OF YOUR WORK (no work – no points). You also must show ALL relevant reactions (equilibria and/or 100% complete). State any assumptions you are making. Unless stated otherwise, assume the temperature is 25°C. Report answers to three significant figures. Circle your final answers. Problem 1. (15 pts.) Determine the change in the boiling point of a solution that has 30.00 g of Mg(NO3)2 (148.32 g/mol) dissolved in 100.0 g of water. (Give
