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.
