Question

explain the following terms
1. mole fraction
2. molarity
3. morality
​

Answer 1

Answer:

Explanation:Mole fraction:It is the ratio of number of moles of one component to the total number of moles present in that solution. Molality:Molality of any solution is represent the number of moles of solute present in per kg solvent. Molarity:Molarity of any solution is number of moles of solute per liter of solution.

Answer 2

Answer:

Mole fraction: it is defined as moles of one substance by the total number of moles.

Molarity: it is defined as moles of solute present in 1L of solution.

Molarity = moles of solute/ volume of solution (in litres).

Molality = moles of solute/mass of solvent in kg

OR

Molality= moles o of solute/mass of solvent in g × 1000
