no.of mole atom of Cl2
Mass of Cl2 = 20 g
Molar mass of Cl2 = 35.5 x 2 = 71 g mol-1
No. of moles of Cl2
= (20/71) mol
Each Cl2 molecule contains 2 Cl atoms.
No. of moles of Cl atom
= (20/71) x 2
= (40/71) mol
= 0.563 mol
=====
no.of mole molecule of Cl2
Mass of Cl2 = 20 g
Molar mass of Cl2 = 35.5 x 2 = 71 g mol-1
No. of moles of Cl2
= 20/71
= 0.282 mol
=====
no.of mole ion of Cl2
Cl2 exists as molecules.
There is no ion in Cl2.
No. of moles of ions
= 0 mol
=====
no.of mole p+ of Cl2
No. of moles of Cl atoms = (40/71) mol
Each Cl atom has 17 protons.
No. of moles of protons
= (40/71) x 17
= 9.58 mol
=====
no.of mole neutron of Cl2
No. of moles of Cl atoms = (40/71) mol
Relative atomic number = Number of protons + Average number of neutrons
35.5 = 17 + Average number of neutrons
Average number of neutrons = 35.5 - 17 = 18.5
No. of moles of neutrons
= (40/71) x 18.5
= 10.4 mol
=====
no.of mole e- of Cl2
No. of moles of Cl atoms = (40/71) mol
Each Cl atom has 17 electrons.
No. of moles of electrons
= (40/71) x 17
= 9.58 mol
=====
no.of atom of Cl2
No. of moles of Cl atoms = (40/71) mol
Avogadro number = 6.02 x 1023
No. of Cl atoms (in Cl2)
= (40/71) x (6.02 x 1023)
= 3.39 x 1023 atoms
=====
no.of molecule of Cl2
No. of moles of Cl2 molecules = (20/71) mol
No. of Cl2 molecules
= (20/71) x (6.02 x 1023)
= 1.70 x 1023 atoms
=====
no.of ion of Cl2
No. of moles of ions in Cl2 = 0 mol
No. of ions in Cl2
= 0 ions
=====
no.of p+ of Cl2
No. of moles of protons = (40/71) x 17
No. of protons
= (40/71) x 17 x (6.02 x 1023)
= 5.77 x 1024 protons
=====
no.of neutron of Cl2
No. of moles of neutrons = (40/71) x 18.5
No. of neutrons
= (40/71) x 18.5 x (6.02 x 1023)
= 6.27 x 1024 neutrons
=====
no.of e- of Cl2
No. of moles of electrons = (40/71) x 17
No. of electrons
= (40/71) x 17 x (6.02 x 1023)
= 5.77 x 1024 electrons
=
