The equivalent weight of a certain trivalent element is 20 ....

The equivalent weight of a certain trivalent element is 2020. Molecular weight of its oxide is

Options

  1. A152152
  2. B5656
  3. C168168
  4. D6868

Correct answer

C. 168168

Step-by-step solution

Equivalent weight = molecular weight  valence factor ∴=\frac{\text { molecular weight }}{\text { valence factor }}\therefore Molecular weight =20×3=60=20 \times 3=60 It's oxide is M2O3\mathrm{M}_{2} \mathrm{O}_{3} and molecular weight =2 ×\times60+16 ×\times3=120+48=168
