A. An empirical formula represent a molecule. B. an empirical formula gives the smallest whole number ratio of each type of atom in a MOLECULE. C. The molecular formula can be the same as the empirical formula in some situations. D. An empirical formula must be multiplied by an integer to obtain the molecular formula.
This information is used to calculate the empirical formula for a compound. The empirical formula is the simplest whole number ratio of atoms in a molecule. Example: Chemical analysis of a liquid shows that it is 60.0% Carbon, 13.4% Hydrogen, and 26.6% Oxygen by mass. Calculate the empirical formula of the substance.or example, if you have 0.50 moles of carbon atoms, how many atoms is that? 6.02 x 1023 atoms Carbon. 0.50 mol Carbon X -------------------------------------- = 3.01 x 1023 atoms Carbon. 1 mol Carbon. You can also convert from atoms to moles.
