Solution:
Given: molecular formula of oxide is M2O3, equivalent mass of metal is 9
To find: molecular mass of the oxide
Explanation:
The equivalent mass of the metal is given as 9, which means that 9 grams of the metal will combine with 1 gram of hydrogen or its equivalent.
The formula of the oxide is M2O3, which means that it contains 2 atoms of metal and 3 atoms of oxygen.
Let the atomic mass of the metal be x.
Therefore, the equivalent mass of the metal, which is given as 9, can be calculated as follows:
9 = x/2
x = 18
The atomic mass of the metal is 18.
Now, to find the molecular mass of the oxide, we need to calculate the sum of the atomic masses of all the atoms present in the molecule.
The formula of the oxide is M2O3, which means that it contains 2 atoms of metal and 3 atoms of oxygen.
The atomic mass of the metal is 18, and the atomic mass of oxygen is 16.
Therefore, the molecular mass of the oxide can be calculated as follows:
Molecular mass of the oxide = (2*18) + (3*16)
= 36 + 48
= 84
Therefore, the molecular mass of the oxide is 84.
Answer: The molecular mass of the oxide is 84.

The formula of the oxide is M2O3, which means that it contains 2 atoms of metal and 3 atoms of oxygen.
The atomic mass of the metal is 18, and the atomic mass of oxygen is 16.
Therefore, the molecular mass of the oxide can be calculated as follows:
Molecular mass of the oxide = (2*18) + (3*16)
= 36 + 48
= 84
Therefore, the molecular mass of the oxide is 84.
Answer: The molecular mass of the oxide is 84.

eq mass= atomic wt/valency factor. M2O3 ( 2M+3 +3 O --2).ie, valency of metal=3. atomic mass of metal= 9×3= 27. mol wt of oxide= 27×2+ 16×3= 54+48=102.
