Asked by Kaustubh Punit | 29 Jul, 2014, 09:50: AM
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
