Assuming equal concentrations and complete dissociation, rank these aqueous solutions by their freezing points from highest to l
muminat

Answer:

NH4Cl > Li2SO4 > CoCl3

Explanation:

Let us recall that the freezing point depression depends on the molality of the solution and the number of particles present.

Let us also recall that freezing point depression is a colligative property. It depends on the number of particles present in solution.

Usually, the more the number of particles present, the lower the freezing point. Hence, NH4Cl which has only two particles will have the highest freezing point while CoCl3 which has four particles will have the lowest freezing point.

How many molecules are equal to 10.35 g of pyridine?
Lera25 [3.4K]

Answer:

0.78× 10 ²³ molecules

Explanation:

Given data:

Mass of pyridine = 10.35 g

Number of molecules = ?

Solution:

Number of moles of pyridine:

Number of moles = mass/molar mass

Number of moles = 10.35 g/ 79.1 g/mol

Number of moles = 0.13 mol

Number of molecules;

1 mole contain 6.022× 10 ²³ molecules

0.13 mol × 6.022× 10 ²³ molecules / 1mol

0.78× 10 ²³ molecules
