Recall that the empirical formula is the simplest whole number ratio formula of a compound. On the other hand, the molecular formula is the unsimplified and actual formula of a compound.
To identify a molecular formula, we need to check if the formula of a compound can be simplified further. This means we need to check if we can divide the formula by a whole number.
Some of the formulas below could be either molecular or empirical formulas: however, some could only be molecular formulas. Which of the following formulas must be molecular formulas? Select all that apply
