Answer #1

The number of formula units in 1.00 mol sample of CaO = Avogadro's number of formula units = 6.02 x 1023

Therefore, the number of formula units in 9.40 mol of CaO = 9.40 mol x 6.02 x 1023/1.00 mol

                                                                                              = 5.66 x 1024
