Colligative property definition chemistry
Vadim26 [7]

Answer: Colligative properties are those properties of solutions that are dependent on the concentration of the solutes in the solution.

Colligative properties has to do with solutions, that is, solutes that are dissolved in solvents. Examples of colligative properties are: freezing point depression, vapour pressure lowering, boiling point elevation and osmotic pressure. Colligative properties do not depend on the identity of the solutes, this implies that the effect of colligative properties are uniform across all solutions. For example, the freezing point depression of any solution will depend on the concentration of solutes that are dissolve in solution.

How many grams of NCI3<br> are in 4.00 moles of NC13?
TEA [102]

The mass of NCl3 in 4.00 moles of NCl3 is 481.44 grams

Mole is defined as the amount of the substance containing the same number of discrete entities (atoms, molecules, ions, etc) as there are atoms in a sample of pure 12C weighing exactly 12g. The number of particles present in one mole of any substance =Avogadro Number=6.

The formula for number mole is given as:

Number of moles =  <u>Mass of the substance </u> ; Now substituting the values

                                   Molar mass

⇒ 4.00 =  <u>x        </u>                       [Molar mass of NCl3 = 120.36]

               120.36

⇒ x = 4.00 × 120.36

⇒ x = 481.44 grams

Therefore the mass of NCl3 is 481.44 grams
