The freezing point-Jillian
What is the freezing point of LiF?
Lithium fluoride has the molecular formula of LiF. LiF has a molecular weight of 25.94 grams per mole and melting point of 845 degrees Celsius.
Is there any chemical way to keep mercury below its freezing point for storage?
It is not necessary to freeze mercury for storage.
How many grams of ethylene glycol automobile antifreeze C2H6O2 dissolved in 3.80kg of water is needed to lower the freezing point of water in an automobile radiator to 21.0C?
None. The freezing point of pure water is already lower than that.

The freezing point of a solution containing 4.12 g of unknown solute in 100 grams of camphor is 166.2 degrees C what is the freezing point depression?
f.p depression = (freezing point of pure solvent)-(freezing point of solution) -------> 178.4-166.2=12.2
What is the molecular mass of 8.02 grams of solute in 861 grams of water lower the freezing point to -0.430 degrees C?
Calculate the molecular mass of the nonionic solutes. 8.02 grams of solute in 861 grams of water lower the freezing point to -0.430 ±C.
Does sugar the time it takes water to freeze?
The freezing point of solution is always less than that of the freezing point of the pure solvent. The freezing point of pure water is 0 (zero) degree celsius. The freezing point of the water decreases with the increase in the sugar concentration. for ex. a 10 grams of sugar when dissolved in 100 grams of water, the freezing point depression of -0.56 degree Celsius A 10 molal sucrose will bring about the depression in freezing point of water to about -20 degree celsius
Does sugar water affect the time it takes to freeze?
The freezing point of solution is always less than that of the freezing point of the pure solvent. The freezing point of pure water is 0 (zero) degree celsius. The freezing point of the water decreases with the increase in the sugar concentration. for ex. a 10 grams of sugar when dissolved in 100 grams of water, the freezing point depression of -0.56 degree Celsius A 10 molal sucrose will bring about the depression in freezing point of water to about -20 degree celsius
How many grams of sugar must be dissolved in 300 grams of water in order to change the freezing point 2.5 degrees Celsius?
13.643224

It is not necessary to freeze mercury for storage.
What is the change in the boiling point and freezing point of 500 grams of water if 45 grams of glucose C6H12O6 were dissolved in it?
This quantity is equivalent to 90 g glucose / kg water = 0.50 mole particles of solute / kg water, so with a 'molar cryoscopic constant' for water of -1.86 oC/kgthis lowers the freezing point to -0.93 oC.
How many grams of ethylene glycol automobile antifreeze C2H6O2 dissolved in 3.80kg of water is needed to lower the freezing point of water in an automobile radiator to 21.0C?
None. The freezing point of pure water is already lower than that.
