Passage / Comprehension

Silicon forms a very large number of compounds containing $SiO_{4}^{4 -}$ anion as the basic unit. The structure of this basic unit is a tetrahedron in which oxygen atoms are arranged in a tetrahedral around the silicon atom.

(atomic weights of Si = 28, Mg = 24, O = 16, H = 1, Al = 27, Be = 9)

The weight percentage of unshared oxygen (univalent charge)in the total weight of oxygen in beryl $[Be_{3} Al_{2} Si_{x} O_{18}]$ is $____$ .

Answer:

66.60

Solution:

$[Be_{2} Al_{2} Si_{6} O_{18}]$

Unshared oxygens are 12.
