It depends on the molecule! If you have a molecular formula for a molecule and the formula does not contain parentheses, you can find the number of atoms in it by adding all the subscripts, treating no subscript as the number 1. If the formula does contain parentheses, first multiply any subscript within the parentheses by the subscript at the end of the parentheses, then add these modified numbers to those of any other atoms in the formula that are not in parentheses.
