What is molal depression constant?
It is defined aste depression in freezing point of solution containing non-volatile solute.wen molality is equal to 1 and is caled molal depression constant i.e. Tf=kf . m
How 1 molal urea solution is equal to 0.5 molal NaCl solution?
Uric acid is an entirely different compound than salt, so I do not see how there is an equivalence between the two.
The molal freezing point constant kf is a property of the solvent not the solute What does this say about the fact that freezing point depends on the amount of solute rather than solute's nature?

What is the molality of a solution that contains 5.10 mol KNO3 in 4.47 kg water?
Molality = moles of solute / kilograms of solventm = 5.10 / 4.47m = 1.14 molal
How do you make 0.1M zinc nitrate?
You make a 0.1 Molal solution of Zn(NO3)2 by weighing 0.1 mole of the salt and dissolving it in 1 kg of water.
What is the molar freezing point constant?
molal
What are the materials for salt water freeze?
Salt lowers the freezing point of water by the amount of molals of NaCl in the solution. 0°C - 1.86(°C / molal) (NaCl molal). This will find the new freezing point and if the energy is enough to bring salt water below this temperature and turn the solution into ice then the salt water will freeze.

Is the molal and molar solution of NaCl the same?
yes

What is the boiling point of a 2.0 molal solution of glucose?
The boiling point is 101 oC.
An aqueous KNO3 solution is made using 89.9g of KNO3 diluted to a total solution volume of 1.35L?
1.0 molal
What is the freezing point of 0.9 percent normal saline?
The melting point of water is lowered by 1.85 degrees Celsius if 29.2 grams of salt are dissolved in each Kg of water (called a "0.5 molal solution" of salt). So normal saline, a 0.9 molal solution), is lowered juts less thantwice this or 3.33 deg C. So normal saline freezes at -3.33 deg C or 26 deg F.
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
What mass of Kl is contained in 2.5L of water if the solution is labeled 2 molal?
Aprox. 830 g.
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
What is the molality of a solution that contains 2 moles of glycerin and dissolved in 1000 g of water?
Moles of solute/ kg of solvent = 2 molal solution
