How many atoms are represented by one formula unit of aluminum dichromate Al2 Cr2O7 3?
29 atoms; --Al2(Cr2O7)3 Since the three is by itself outside the parentheses, it has to be distributed. To do this, you just take the two from Cr times three, which of course gives you SIX. Then you take the seven from O times the three, and you get TWENTY-ONE. Then you just have to add the TWO from Al to it. So, 6+21+2=29.
