00:01
So we've decoded the mass of 500 atoms of iron.
00:04
Okay, so first of all from a test book, the model mass of atom is 55 .8 gram per mole.
00:10
So in other words, for each mole of iron, we will have 55 .85 gram.
00:15
Okay, so what would be the mass of one single atom? and then from there, we can find out the mass of 500 atoms.
00:27
So this will be the third chart of our calculation.
00:30
So first of all, for one single iron atom, the mass would be, equals to the bottom mass, 55 .85 quorum, divided by the average number...
