The volume of water to be added to N 2 HCl to prepare 500 ~cm ³ of N 10 solution is

Options

  1. A450 ~cm ³
  2. B100 ~cm ³
  3. C45 ~cm ³
  4. D400 ~cm ³

Correct answer

B. 100 ~cm ³

Step-by-step solution

Moles of HCl = 1 2 V N 2 HCl For preparing N 10 solution, aligned & 1 10 = 1 2 V 500 V &= 1000 10 =100 ~cm ³ aligned
