a) Calculate the amount of sodium chloride required to prepare 40 mL of a concentrated solution so that when it is diluted 1 in 20 with water, the resulting solution is isotonic. Sodium chloride AT1% = 0.576 %D (using freezing point depression formula ΔΤΑ- ΔΤ1%xC) b. Give the freezing point depression for the concentrated solution. c. Indicate how the concentrated solution is prepared (eg. order of addition) to achieve the correct concentration.
