The value of n in the molecular formula ...

The value of `n` in the molecular formula `Be_(n)Al_(2) SiO_(18)` is …..

Text Solution

Verified by Experts

The correct Answer is:
C
`Be_(n) Al_(2) Si_(6) O_(18)`
`(2n) + (3 xx 2) + (4 + 6) + (-2 xx 18) = 0`
or `2n + 30 - 36 = 0`
or `2n = 6`
or `n = 3`
