The value of n in the molecular formula ...

The value of `n` in the molecular formula `Be_(n)Al_(2) Si_( 6)O_(18)` is …..

Text Solution

Verified by Experts

The correct Answer is:
`(3)`
The value of `n` in the molecular formula `Be_(n) Al_(2) Si_(6) O_(18)` is `3`.
`2n + (2 xx 3) +(4 xx 6) +(18 xx -2) = 0`
or `n = 3`.
Beryl is `Be_(3)Al_(2)Si_(6) O_(18)`.
