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