Molal freezing point constant of water is:
- A
1.86
- B
2.86
- C
11.86
- D
0.52
The molal freezing point depression constant for H2O, Kf , is given as 1.86 °C kg/mole.
Thus a 1.00 m aqueous solution freezes at -1.86 °C instead of 0.00 °C which is the normal freezing point for water.
This is the correct value for the molal freezing point constant of water, known as the cryoscopic constant, which is approximately 1.86°C/m.
This value is too high for the molal freezing point constant of water. The correct constant is 1.86°C/m.
This value is much too high. The correct molal freezing point constant for water is 1.86°C/m.
This value is too low. The correct molal freezing point constant for water is 1.86°C/m.
