Question

The freezing point of water is 0.00 °C at 1 atmosphere.

A student dissolves 11.60 grams of cobalt(II) sulfate CoSO4, (155.0 g/mol), in 279.3 grams of water. Use the table of boiling and freezing point constants to answer the questions below.

Solvent	Formula	K_b(C/m)	K_f(C/m)
Water	H2O	0.512	1.86
Ethanol	CH3CH2OH	1.22	1.99
Chloroform	CHCl3	3.67
Benzene	C6H6	2.53	5.12
Diethyl ether	CH3CH2OCH2CH3	2.02

The molality of the solution is m.

The freezing point of the solution is °C.
