Emperical Formula - A formula that gives the simplest whole number ratio of atom in a compound.
In the question percentages are given then assume that the total mass is 100grams so that the mass of each element is equal to the percentage given.
Given : 80.0g Carbon
20.0g Hydrogen
First convert the given masses into moles.
Value of each mole divided by the smallest number of moles and then round off.
Moles ratio of the element are
This is the mole ratio of the elements and is repersented by the subscript in the emperical formula.
Emperical Formula =
