hey!!
molarity=no of moles of solute/vol of soln in lotre
molality=no of moles of solute /weight of solvent in kg
normality=no of gram equivalents / vol of soln
no of gram equivalents=given mass/ equivalent mass
equivalent mass=molecular mass/n factor

hope this is helpful to u

Answer :

Here are important formulae from mole concept :-

1.Number of moles = Mass of substance in grams / Gram molecular mass of substance.

2. Number of atoms = Mass of substance × Avagadro no./atomic mass

3. No. of moles = Given mass / molar mass. ( same as 1. )

4.Mole fraction = Moles of solute or solvent / moles of solute + moles of solvent.

5. Molality = moles of solute / kg of solvent.

6. Molarity = moles of solute / litres of solution

7. Strength of solution = grams of solute / Solution in L
