3.5B . Plan The mass of calcium phosphate is converted to moles of calcium phosphate by dividing by the molar mass. Avogadro's number is used to change the number of moles to formula units. Each formula unit has two phosphate ions, so the total number of phosphate ions is two times the number of formula units. Solution
