Question

calculate number of electrones present
in gos g of Po-³4​

Answer 1

• you have 0.1 mol PO4 3-
• you have 0.1 mol PO4 3-Electrons in 1 P atom = 15.
• you have 0.1 mol PO4 3-Electrons in 1 P atom = 15.Electrons in 1 O atom = 8.
• you have 0.1 mol PO4 3-Electrons in 1 P atom = 15.Electrons in 1 O atom = 8.Electrons in 4 O atoms = 32.
• you have 0.1 mol PO4 3-Electrons in 1 P atom = 15.Electrons in 1 O atom = 8.Electrons in 4 O atoms = 32.Total = 47 electrons + 3 for 3- charge = 50 electrons / ion.
• you have 0.1 mol PO4 3-Electrons in 1 P atom = 15.Electrons in 1 O atom = 8.Electrons in 4 O atoms = 32.Total = 47 electrons + 3 for 3- charge = 50 electrons / ion.Number of electrons in 0.1 mol ions :
• you have 0.1 mol PO4 3-Electrons in 1 P atom = 15.Electrons in 1 O atom = 8.Electrons in 4 O atoms = 32.Total = 47 electrons + 3 for 3- charge = 50 electrons / ion.Number of electrons in 0.1 mol ions :Number = 50 * 0.1 * 6.022*10^23 = 3.01*10^24 electrons.
