If you dissolve 89.0g of sodium sulfate in 1.5 l of water , what is the molarity of the resulting solution ?

             Molarity  =  0.4 mol.L⁻¹

Solution:

Molarity is given as,

                         Molarity  =  Moles / Volume of Solution
Also,
                         Moles  =  Mass / M.mass
So,
                         Molarity  =  Mass / (M.mass × Volume of Solution)

Data Given,
                   Mass  =  89 g

                   M.mass of Na₂SO₄  =  142 g.mol⁻¹

                   Volume  =  1.5 L

Putting Values,
 
                    Molarity  =  85 g ÷ (142 g.mol⁻¹ × 1.5 L)

                    Molarity  =  0.399 ≈ 0.4 mol.L⁻¹

No is the answer to the question

Okay well gravitational energy is matter forced by gravity making energy though the kinetic energy then the electric energy produces electricity from the kinetic energy and the kinetic energy gets its energy from the gravitational energy. was that the answer you wanted or something else?
