Answer 1

Answer:

Empirical formula = $C_{3}$ $H_{8}$ O

Explanation:

From the above question,

They have given :

An organic compound contains carbon, hydrogen, and oxygen.

It's elemental analysis gave C, 60% and H, 13.33% and O, 26.66%

The empirical formula of a compound is the simplest whole-number ratio of atoms of each element present in the compound.

It is determined by analyzing the element composition of the compound. The empirical formula of a compound can be calculated by dividing the mass of each element by its atomic mass and then dividing the resulting number by the smallest number obtained.

The empirical formula for the compound can then be determined from the resulting ratios.

Elements %            No. of moles            Simple ratio

C = 60 %                 60 / 12 = 5                      3

H = 13.3 %               13.3 / 1 = 13.3                   8

O = 26.7 %           26.7 / 16 = 1.66                   1

Empirical formula = $C_{3}$ $H_{8}$ O
