If 2 0 ~g of NaOH is dissolved in 500 ~cm ³ of water, what is molarity of solution?
Options
- A0 25 ~mol dm ⁻³
- B0 1 ~mol dm ⁻³
- C0 4 ~mol dm ⁻³
- D0 50 ~mol dm ⁻³
Correct answer
B. 0 1 ~mol dm ⁻³
Step-by-step solution
Molarity =0.10 mol L ⁻¹ with respect to NaOH Explanation: Molarity = Moles of solute Volume of solution Molarity = 2 g 40.0 g m o l⁻¹ 1 500 mL 10⁻³ L mL⁻¹ Molarity =0.1 ~mol dm ^ -3
