Formula showing the simplest possible ratio of atoms in a molecule
Can be determined if the percent composition, the moles of each component element, or the
grams of each component element is known
Steps to determine (empirical):
1
...
Treat % as grams and then convert grams of each element to moles of each element
3
...
If the ratio is not composed of all whole numbers, multiply each by an integer so that all
the elements are in a whole number ratio
Steps to determine (molecular):
1
...
Find the mass of the empirical formula
3
...
Multiply the subscripts in the empirical formula by the quotient to determine the
molecular formula
