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. What was the mass of CaCl2(s) that the students added to the 2nd test tube? Question 3 options: 3.09 1.09 1.87 2.03 2.63 1.61 0.86 2.24 2.87 2.40 1.25 1.42
