The molecular mass of iodide of tin (Sn)...

The molecular mass of iodide of tin `(Sn)` is 626.5 amu. What is the empirical formula of the substance?
`(I = 127, Sn = 118.5)`

Text Solution

Verified by Experts

Let the formula iodide of `SN = SnI_(x)`
Since the valency of Iodile `= -1`
`:. SnI_(x) = 118.5 + 127 xx x = 625.5`
Solve for `x`:
`:.x = 4`
Formula `= SnI_(4)`
