Question

Consider the following silicates ,

(a) $BaTi\left(S{i}_3{O}_9\right)$

(b) $ZnC{a}_{2}S{i}_2{O}_7$.

Then calculate $X÷Y$ where X and Y are total number of monovalent and divalent oxygen atoms in both silicates respectively.

Answer 1

(a) For $BaTi\left(S{i}_3{O}_9\right)$, the number of monovalent oxygen atoms (X) is 6 and the number of divalent O atoms (Y) is 3.

(b) For $ZnC{a}_{2}S{i}_2{O}_7$ the number of monovalent oxygen atoms (X) is 6 and the number of divalent O atoms (Y) is 1.
Hence, total $X=6+6=12$ and total $Y=3+1=4$

Thus, $\frac{X}{Y}=\frac{12}{4}=3$
