The empirical formula and molecule mass of a compound are `CH_(2)O` and 180g respectivel. What will be the molecular formula of the compound?

Options

A. `C_(9)H_(18)O_(9)`
B. `CH_(2)O`
C. `C_(6)H_(12)O_(6)`
D. `C_(2)H_(4)O_(2)`

Answer

C

Explanation

Empirical formula mass `= CH_(2)O`
`=12+2xx1+16=30`
Molecular mass =180
`n=("Molecular mass")/("Empirical formula mass")`
`=(180)/(30)=6`
`therefore` Molecular formula =nxx amp rical formula
`=6xxCH_(2)O`
`=C_(6)H_(12)O_(6)`
