Question

What is the concentration of a 0.750 l solution that contains 52.0 g of glucose (c6h12o6)?

Answer 1

Concentration of Solutions is oftenly expressed in Molarity. Molarity is the number of moles of solute dissolved per volume of solution.

                             Molarity  =  Moles / Volume
As,
      Moles  =  Mass / M.mass
So,
                             Molarity  =  Mass / M.mass × Volume   ---- (1)

Data Given;
                   Volume  =  0.750 L

                   Mass  =  52 g

                   M.mass  =  180 g/mol

Putting Values in eq.1,

                     Molarity  =  52 g ÷ (180 g.mol⁻¹ × 0.750 L)

                     Molarity  =  0.385 mol.L⁻¹
