The molecular formula of a non-stoichiometric tin oxide containing Sn (II) and Sn (IV) ions is Sn4.44O8.
Therefore, the molar ratio of Sn (II) to Sn (IV) is
Approximately
A
1 : 8
B
1 : 6
C
1 : 4
D
1 : 1
Answer
1 : 4
Explanation
Solution
Let in one mole of the given substance the number of moles of Sn (II) = x moles and number of moles of Sn (IV) = y moles.
\ x + y = 4.44 and 2x + 4y = 16
By solving x = 0.88 and y = 3.56
\mole ratio of Sn (II) to Sn (IV) is 0.247:1 ~ 1 : 4
