What is the molarity of solution containing 0 8 ~g of NaOH (Molar mass 40 ~g ~mol ⁻¹ ) in 150 ~cm ³ of water?

Options

  1. A0 02 ~mol dm ⁻³
  2. B0 12 ~mol dm ⁻³
  3. C5 33 ~mol dm ⁻³
  4. D0 1333 ~mol dm ⁻³

Correct answer

D. 0 1333 ~mol dm ⁻³

Step-by-step solution

n = 0.8/40 = 0.02 Volume = 0.15 ~L Molarity = 0.02 /0.15 = 0.133 ~mol ~dm⁻³
