What would the final freezing point of water be if 3 mole of sugar were added to 1 kg of water?
The CHANGE in freezing point can be determined from ∆T = imK where ∆T is the change in freezing point, i is van't Hoff factor (1 for sugar, a non electrolyte), m is molality (moles solute/kg solvent), and K is the freezing point constant for water (1.86). Thus ∆T = (1)(3)(1.86) = 5.58ºC. So, the FINAL freezing point will be -5.58ºC
How much would the freezing point of water decrease if 4 mole of Na Cl were added to 1 kg of water?
The freezing point decrease is -14,8 oC.
What happens to the freezing point of pure water when salt is added to it?
it lowers it. impurities lower the melting and raise the boiling point of substances. they also cause the melting point to fall over a range now. for example, water's melting point was initially 0 but upon adding salt it now is -5 to -1 degrees celsius.
Why The freezing point of salty water is less than that of pure water?
Depression in freezing point is a colligative property of solutions. When salt(solute) is added to the water(solvent), the vapor pressure of the water decreases. As a result, the freezing point of the water is lowered and hence salt water takes longer to freeze than pure water.
Which ionic compound will lower the freezing point the most of 1 mol of it is added to 1 mol of it is added to 1 L of water?
NaCl

When antifreeze is added to water the freezing point of the water is what?
It drops to about 12 degrees Fahrenheit.

The freezing point decrease is -14,8 oC.
How much would the freezing point of water decrease if 4 moles of Na-Cl were added to 1 Kg of water?
The freezing point decrease is -14,8 oC.
How much would the freezing point of water decreases if 4 mol of sugar were added to 1kg of water?
The normal freezing temperature for pure water is 0c. Howeverif sugar is added in the pure water, the freezing point will be lower than zero. How far below zero will depend on the sugar concentration in the water.

What occurs when NaCl is added to water?
The boiling point of the solution increases, and the freezing point of the solution decreases.
Why does the freezing point of water lower when solute is added?
the solute gets in the way of the water turning to ice

What is meant by the medical term or ailment 'freezing point depression'?
Freezing point depression is not a medical term, but a term of physics. It refers to the scientific concept of when the freezing point of a liquid is lowered by adding something to it. For example: The freezing point of water is 0 degrees Celcius, but if salt is added to water, the freezing point is lower, and will still be a liquid at 0 degrees.
