Step 1: Conversion of mass percent to grams
Step 2: Calculate the number of moles of each element.
Moles of an element = Mass of element in grams / Atomic mass of the element
The moles of different elements thus calculated represent the relative number of moles.
Step 3: Calculate the simplest molar ratio
Step 4: Write the empirical formula
