A certain liquid X has a normal freezing point of 1.20C and a freezing point depression constant Kf=6.65Ckg mol 1, A solution is prepared by dissolving some sodium chioride (NaCl) in 900 . g of X. This solution freezes at 7.7C. Calculate the mass of NaCl that was dissolved. Round your answer to 2 significant digits. Four liquilds are described in the table below. Use the second column of the table to explain the order of their freezing points, and the third column to explain the order of their boiling points. For example, select ' 1 ' in the second column next to the liquid with the lowest freezing point, Select '2' in the second column next to the liquid with the next higher freeting point, and so on. in the third column, select ' 1 ' next to the liquid with the lowest bolling point, '2' next to the liquid with the next higher boiling peint, and so on. Note: the density of water is 1.00g/ml
