Cl2O7. To find the number of moles divide 6.02 x 10^23 by 9.64x10^24, then multiply the number of moles by the molecular weight of Cl2O7.

grams Cl2O7 = number of molecules/avogadro's number times the molecular weight of Cl2O7
avogadro's number is 6.022 x 10^23.
molecular weight of Cl2O7 two times mol wt chlorine plus seven times the mol wt of oxygen.

at wts:
Cl=35.45
O=16
mole wt:
2*35.45+7*16=70.9+112=182.9g/mole
96.4/6.023=16 moles
182.9 g/mole*16 moles=2967g
