The oxide of an element possess the molecular formula M2O3. If the equivalent mass of the metal is 9, the molecular mass of the oxide will be- |
|
Answer» SINCE valancy FACTOR of metal is 3 so ATOMIC weight of metal = 3*equivalent mass . . . . = 3*9=27 Atomic mass of O= 16 so O3 = 48 So the molecular weight of M2O3 = 2*27+3*16=102 |
