The empirical formula of a non-electroly...

The empirical formula of a non-electrolyte is `CH_(2)O`. A solution containing 3 g `L^(-1)` of the compound exerts the same osmotic pressure as that of 0.05 M glucose solution. The molecular formula of the compound is :

`CH_(2)O`

`C_(2)H_(4)O_(2)`

`C_(4)H_(8)O_(4)`

`C_(3)H_(6)O_(3)`
