The empirical formula and molecular mass of a compound are `CH_(2)O` and 180 g respectively. 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 formual mass `=CH_(2)O = 12+2 +1 xx 16= 30`
Molecular mass= 180 `n= ("Molecular Mass")/("Empirical formula mass")= (180)/(30)=6`
`therefore` Molecular formula `= n xx` empirical formula
`because` Molecular formula `=6 xx CH_(2)O = C_(6)H_(12)O_(6)`
