Question

16. A compound contains 4 gm Hydrogen,
24 gm carbon and 32 gm oxygen. it's molar
mass is 180 gm/mol. what are its molecular
formula. *
O CH20
CH02
O C6H1206
O C6H1004​

Answer 1

Explanation:

step 1

Divide the given percentages of atoms with their molecular masses

H---4.07/1 =4.07

C---24.27/12 =2.02

Cl--71.65/35.5=2.01

step 2

divide all values with the lowest value obtained.

H---4.07/2.01=2

C---2.02/2.01=1

Cl---2.01/2.01=1

therefore the empirical formula is

CH

2

Cl

WEIGHT OF EMPIRICAL FORMULA=12+2+35.5=49.5

Given molecular weight =98.96 which is double of empirical weight .therefore molecular formula is C
