What is the predicted melting point if 1.2 g of salt is added to 10 mL of water? Justify your answer.

Answer:

depression in freezing point is directly proportional to molality (mass of solute when the amount of solvent remains same)

0.3 g depression is 1.9 ^o C

0.6 g depression is 3.8 ^o C

1.2 g depression will be 3.8 x2 = 7.6 ^o C
