Question

a compound containing carbon hydrogen and oxygen gave the following analytical data is equal to 40% at equal to 6.67% calculate the molecular formula of compound if molecular mass is equal to 180 plzzz plzzz tell​

Answer 1

Explanation:

For this we make a table as:

Element

%Composition

Atomic Mass

Mole Ratio

Simple Ratio

C

40.00%

12

(40/12)

(3.33/3.33)=1

H

6.67%

1

(6.67/1)

(6.667/3.33)=2

O

53.33%

16

(53.33/16)

(3.33/3.33)=1

∴ Formula of compound is =CH

2

O
