Answer 2

What is empirical formula?

- It is the molecular formula of a compound in the lowest terms.

What is empirical mass ?

- Relative molecular mass of empirical formula of a compound is called empirical mass of that compound.

To find,

Empirical formula of CH3COOH ( Acetic acid ) and it's emporical mass

Solution:

In this chemical formula,

No. of atoms of C = 2

No. of atoms of H = 4

No. of atoms of O = 2

Ratio of no. of atoms of these three elements in this compound = 2:4:2

Now, reducing this to lowest terms we get :-

1:2:1

Empirical formula is :- CH2O

It's empirical mass = 12 + (2×1)+16 = 30u
