So in Magnesium has a neutron number of 12 and so like it says above. Each of the neutron is 1/24 which is 1g

One mol of 24M is 24g. There are 12 neutrons per atom of Mg. Each neutron is 1/24th of the Ar of Mg so one mole is 1/24th of 24g which is 1g. I hope that makes sense.
Ar=24 therefore 1 mole of mg= 24g
Neutron n.o= 12 = 12gmol-1 and there are 12 moles of neutrons per mole of Mg
for 2g of mg, (24 divide by 12 = 2) therefoe 12 divide by 12 = 1g.
therefore 12 mole of neutrons divide by 12 = 1 mole.
SO 1 moles of n = 1g
