Given the following information about a copper (II) chloride solution in water, find the mole fraction (of CuCl2), molality (m), molarity (M), new boiling point, and osmotic pressure:
Solution is: 8.23 g of CuCl2 dissolved in 1.35 L of water at 25 degrees C (dwater= 1.00 g/mL, new solution d= 1.23 g/mL), kb(H2O) = 0.52 C/m
