Problem A sample of an unknown compound contains 0.21 mol of zinc, 0.14 mol of phosphorus, and 0.56 mol of oxygen. What is the empirical formula?Plan We are given the amount (mol) of each element as fractions. We use these fractional amounts directly in a preliminary formula as subscripts of the element symbols. Then, we convert the fractions to whole numbers.

Problem Ammonium carbonate is a white solid that decomposes with warming. It has many uses, for example, as a component in baking powder, fire extinguishers, and smelling salts.(a) How many formula units are in 41.6 g of ammonium carbonate?(b) How many O atoms are in this sample?Plan (a) We know the mass of compound (41.6 g) and need to find the number of formula units. we need the formula to find the amount (mol) and then multiply by Avogadro’s number to find the number of formula units. [The road map steps are for part (a).] (b) To find the number of O atoms, we multiply the number of formula units by the number of O atoms in one formula unit.
