Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.

A group of students were weighing some CaCl2(s) but they forgot to record the mass. They know that they had 50 mL of water (you can assume water has a density of 1.00 g/mL) in the 1st test tube and the freezing point for the water by itself was measured to be -0.01 °C. When they added the CaCl2(s) to 50 mL water in a 2nd test tube and measured the freezing point with the same thermometer they got a freezing point of -1.868°C. The Kf value for water is 1.858 °C/m.
