Two oxides of a X contain 50 % and 40 % of non-metal respectively. If the formula of the first oxide is XO ₂ . Then the formula of second oxide is
Options
- AX₂ O ₃
- BX₂ O ₅
- CX O ₃
- DX₂ O
Correct answer
C. X O ₃
Step-by-step solution
In XO ₂, X : O :: 50: 50 Mass of oxygen =2 16=32 ~g Hence, mass of X=32 ~g In XO _n, X : O :: 40: 60 Mass of X , in this case also remains =32 ~g 40 % 32 ~g 60 % 32 40 60=48 ~g Mass of oxygen =48 ~g n= 48 16 =3 Formula of oxide = XO ₃
