calculate the empirical
formula and empirical Formula mass
of the compound . -
​

Answer 1

Answer:

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
