Question

5 gram of NaCl is dissolved in 1000 gram of water. if the density of the resulting solution is 0.997 gram per ml, calculate the molality, molality, normality and mole fraction of the solute, assuming volume of the solution is equal to that of solvent.​

Answer 1

Answer:

water resulting in a 100 g solution. Concentration ... 5 g. 40 g mol. = 0.125 mol. Volume of the solution in litres = 450 mL / 1000 mL L-1 ... 2.5 Calculate (a) molality (b) molarity and (c) mole fraction of KI if the density of 20% ...
