Question

explain the following concentration terms. a)molarity b)morality c)mole fraction

Answer 1

molarity is defined as no of moles of solute dissolved in per litre of solutions
molality is defined as no of moles of solute dissolved in per kg of solvent
Mole fraction of component is defined as ratio of no of moles of components to the sum of no of moles of component in the solution
please comment if it's wrong

Answer 2

Hey !

Molarity :- It is defined as number of moles of solute dissolved in one litre of solution.

Molarity :- Moles of solute / Volume of solution (in litre)

Units of molarity is mol L-1 or M.

Mole fraction :- It may be defined as the ratio of the number of moles of one component (solute or solvent) to the total number of moles of all the components present in the solution.

Molality :- it is defined as the number of moles of the solute dissolved in one kilogram of the solvent.
