3. Calculate the percent by mass of the second element in the properly written formula. Example, for Ferric Hydroxide, the % would be based on the Oxygen from the formula Fe(OH)3 (do not rely on google for your nomenclature since that kept giving FeHO₂, an incorrect formula for the name given.) a. Calcium Acetate b. Ammonium Sulfate c. Iron (II) Nitrate
