The boiling point of diethyl ether, CH3CH₂OCH₂CH3, is 34.50°C at 1 atmosphere. A nonvolatile, nonelectrolyte that dissolves in diethyl ether is estrogen (estradiol). A student dissolves 11.14 grams of estrogen, C18H2402 (272.4 g/mol), in 215.8 grams of diethyl ether. Use the table of boiling and freezing point constants to answer the questions below.
