Answer:
             Moles  =  8 moles

Solution:
              Molarity is given as,

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

Data Given;
                   Molarity  =  2 M

                   Volume  =  4 L

Solving eq.1 for Moles,

                       Moles  =  Molarity × Volume of Solution

Putting values,

                       Moles  =  2 mol.L⁻¹ × 4 L

                       Moles  =  8 moles
