Question

Manganes form non stoichiometric oxodes having general formula mnox

Answer 1

Answer:

Explanation:

The value of X for the manganese oxide is 2 and the formula of the oxide is .

Solution:- We are asked to calculate the value of X which is the subscript of oxygen in the unknown oxide.

From given information, the compound has 63.7% Mn.

percentage of oxygen = 100 - 63.7 = 36.3%

We can calculate the moles for Mn and O as:

= 1.16 mol Mn

and

= 2.27 mol O

Now we could calculate the mol ratio of these two elements as:

=

The mol ratio of Mn to O is 1:2. So, the value of X is 2 and the formula of the oxide
