Expert Answer:

Number of electrons in 1 mole = 6.022 x 1023

There are total 50 eletrons in PO4-3.

1 mole of PO4-3 will contain = 50 x 6.022 x 1023 electrons

1 gram of PO4-3 contains 50 x 6.022 x 1023 electrons

So, 9.5 grams of PO4-3 will contain 9.5 x 50 x 6.022 x 1023 electrons = 2.86 x 1026 electrons
