Explanation / Answer

oxidation state of Cu is 2
oxidation state PO4 is 3
so, formula is
Cu3(PO4)2

molar mass of Cu3(PO4)2 = 380.6 g/mol
number of mole of Cu3(PO4)2 = (given mass)/(molar mass)
= 5.80/380.6
= 0.0152 mole

1 mol of Cu3(PO4)2 has 2 mol of P
0.0152 mol of Cu3(PO4)2 has (2*0.0152) mol of P
number of mole of P = 0.0304 mole

number of mole of P atom = (number of mole of P)*(6.022*10^23)
= 0.0304*6.022*10^23
= (1.83*10^22)

Answer : 1.83*10^22
