(0.12 ~g ) of an organic compound ' (X ) ' containing phosphorus on reacting with magnesia mixture gave (0.22 ~g ) of magnesium pyrophosphate ( ( Mg ₂ P ₂ O ₇ ) ). The percentage of phosphorus in the compound ' (X ) ' is

Options

  1. A(45.30 % )
  2. B(28.70 % )
  3. C(64.25 % )
  4. D(51.20 % )

Correct answer

D. (51.20 % )

Step-by-step solution

Estimation of phosphorus in organic compound is down by using magnesia mixture. It uses the working formula. ( P %= 62 222 w₁ w 100= 62 222 0.22 0.12 100=51.20 % )
