The freezing point of benzene C,H, is 5.50°C at 1 atmosphere. A nonvolatile, nonelectrolyte that dissolves in benzene is TNT (trinitrotoluene). How many grams of TNT, C,H&N3O6 (227.1 g/mol), must be dissolved in 269.0 grams of benzene to reduce the freezing point by 0.400°C ? Refer to the table for the necessary boiling or freezing point constant.

CONCLUSIONS: In general, the boiling points of compounds increase down a group in the periodic table. The melting points and boiling points for the hydrogen compounds of group 6A elements are in the table below. Melting Point (°C) Boiling Point (°C) H₂O 0.0 100.0 H₂S -82.0 -60.0 H₂Se -65.7 -41.2 H₂Te -49.0 -2.2 Use your understanding of chemistry to propose an explanation for the anomaly in the trend for the hydrogen compounds of group 6A elements shown in the table.
