Empirical formula = CH 2 O Empirical formula weight =30 n=(240/30)=8 Molecular formula =( CH 2 O )8 = C 8 H 16 O 8

Q. An. unknown compound has molar mass $240 g / m o l$ . Its empirical formula is $C H_{2} O$ then its molecular formula will be

$C_{4} H_{8} O_{4}$

$C_{12} H_{22} O_{12}$

$C_{6} H_{12} O_{6}$

$C_{8} H_{16} O_{8}$

Empirical formula $= C H_{2} O$
Empirical formula weight $= 30$
$n = \frac{240}{30} = 8$
Molecular formula $= (C H_{2} O)_{8}$
$= C_{8} H_{16} O_{8}$
