Calculate the concentration in mol/L, M, of an aqueous sugar solution with a concUsing the above equation, how many grams of salt ( CaCl2 ) would need to be added to 1 L of water in order for the boiling point of the solution to reach 106 °C ? Assume that the density of water is 1.0 g/mL and that CaCl2 completely dissociates into three ions — i.e., a Ca2+ ion and two Cl− ions. The boiling point constant, kb , for water is 0.515°C/m .entration of 17.0% (w/w) and density of 1.015 g/mL at 25°C . The molecular weight of sugar is 342.30 g/mol. Report your answer to three significant figures.
