(10 ~g ) of ( NaOH ) is dissolved in (500 ~mL ) of aqueous solution. Calculate the molarity of this solution? (Given, formula weight of ( NaOH =40 ) )

Options

  1. A(0.5 10⁻³ M )
  2. B(0.4 M )
  3. C(0.25 10⁻³ M )
  4. D(0.5 M )

Correct answer

D. (0.5 M )

Step-by-step solution

( ) Molarity (= Mass of solute ( in gL ⁻¹ ) Molar of solute ( in g mol ⁻¹ ) ) (= 10 500 1000 40 M =0.5 M )
