Answer :

transitionstate
This problem is being solved using following formula,

                       Molarity  =  Moles / Volume of Solution   ----- (1)

Data Given:
                    Molarity  =  0.1 mol.L⁻¹

                    Volume  =  100 mL  =  0.1 L

                    Mole  =  ?

Solving Eq. 1 for Moles,

                    Moles  =  Molarity × Volume of Solution

Putting Values,

                    Moles  =  0.1 mol.L⁻¹ × 0.1 L

                    Moles  =  0.01 moles
