The relative number of atoms of different elements in a compound are as follows: $$A =$$ $$1.33$$, $$B =$$ $$1$$ and $$C$$ $$=$$ $$1.5$$. The empirical formula of the compound is:

A$$A_{2}B_{2}C_{3}$$
B$$ABC$$
C$$A_{8}B_{6}C_{9}$$
Correct Answer
D$$A_{3}B_{3}C_{4}$$

Solution

Given,

$$A : B : C = 1.33 : 1 : 1.5 $$

Making it in a simple whole-number ratio by multiplying it with 6, we get-

$$= 8:6:9 $$

$$\implies \text {Empirical Formula} = A_8B_6C_9$$

Hence, option C is correct.
