There, in this question we are converting from moles, we are given moles at the start, and we're converting that to number of molecules.
00:17
Anytime we're converting between moles and a number of particles, whether those particles are molecules or atoms or electrons or formula units or even grains of sand, what we need to use is avogadro's number, which is 6 .02 times 10 to the 23rd.
00:36
There are that many molecules in every mole.
00:49
All right, there would be that many if we're working with atoms, there would be that many atoms in one mole.
00:54
Or whatever it is we're working with, there would be that many in one mole of the substance.

So in this question, though, we have five moles, and the specific substance is carbon monoxide, and we want to know how many molecules are there...
