<span>Because copper (II) cations have a charge of +2 and phosphate anions have a charge of -3, the formula of anhydrous* copper (II) phosphate is
Cu3(PO4)2
This shows that each formula unit contains 2 atoms of phosphorus. Therefore, the atoms of phosphorus in 4.8 formula units is
4.8 x Avogadro's Number (</span><span>6.022x10*23)</span>, or about 2.9 X 10*24 atoms
