In this video, we're going to learn how to calculate mass in grams of atoms.
00:07
For the purposes of this example, we are going to use lead.
00:11
And on the screen, i have provided the atomic mass of lead, which is 207 .2.
00:18
Of course, this number, the atomic mass, is the mass in grams of one mole of this element.
00:25
We also know that the mass of a single atom is the atomic mass of that element, divided by all of the atom.
00:32
Avogadro's number.
00:34
This is because the atomic mass is the mass in grams of one mole, and abagadro's number is the number of atoms in one mole.
00:45
Once we have this equation, we just plug in our numbers...
