The equivalent weight of a certain trivalent element is 20 . Molecular weight of its oxide is

Options

  1. A152
  2. B56
  3. C168
  4. D68

Correct answer

C. 168

Step-by-step solution

Equivalent weight = molecular weight valence factor Molecular weight =20 3=60 It's oxide is M ₂ O ₃ and molecular weight =2 60+16 3=120+48=168
