Question

A compound that contains only carbon hydrogen and oxygen is 68.5% C and 8.63% H biomass. What is the empirical formula of this substance

Answer 1

CH32O6

Step-by-step explanation:

To find the empirical formula, first divide the percentage by the mass given in the periodic table.

O= 68.5/16 =4.28125

C= = 8.63/12 = 0.719167

H= (100-(68.5+8.63))/1= 22.87

Now divide all of them by the lowest value:

C= 0.719167/0.719167=1

O= 4.28125/0.719167= 6

H= 22.87/0.719167= 32

Empirical formula= CH32O6
