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
How many moles of urea 60.0 g mol must be dissolved in 100.0g of water to give a 2.5 molal solution?
The answer is 15,015 g.
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.
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 difference between partial molal quantities and partial molar quantities?
During the determination of the partial molal quantities the weight of the solution to which a substance is added is taken into consideration while in case of the partial molar quantity the volume is taken into consideration.
How many grams of lithium sulfide must be dissolved in 1600 grams of water to make a 2 molal solution?
Don't try this at home, since Li2S can react very violently with water (much like lithium or sodium metal in water).

How many grams of hydrogen peroxide (H2O2) must be added to 1,500 mL of water to produce a concentration of 1.33 m (molal solution)? (Recall that the density of water is 1.0 gram/mL
Is the molal and molar solution of NaCl the same?
yes
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.
What does 1M glucose solution mean?
1M glucose means that 1 mole of glucose is dissolved in 1kg of water. Since 1M means 1 molal. And molality is equla to no.of moles of solute per kg of water.
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 mass of Kl is contained in 2.5L of water if the solution is labeled 2 molal?
Aprox. 830 g.
