The empirical formula of a compound is `CH_(2)O`. Its molecular weight is 90. Calculate the molecular formula of the compound.

Text Solution

Verified by Experts

Molecular formula = empirical formula `xx` n
`n=(M.Wt.)/("Empirical formula wt.")`
Empirical formula weight of `CH_(2)O`
= 12 + 2 + 16 = 30
`n=90/30=3`
Molecular formula = `(CH_(2)O)_(3)=C_(3)H_(6)O_(3)`
