So in this example, we're going to be looking at how to convert from atomic mass units to kilograms for a couple of different elements here.
00:11
So the first being hydrogen.
00:13
Now, the easy thing to remember to perform these conversions is just what the conversion factor is going to be from atomic mass units to kilograms.
00:21
And that's going to be that there are 1 .66 times 10 to the minus 27 kilograms.
00:34
Per you.
00:38
And then if you remember this, all you have to do is multiply at times the atomic mass of each element, and you'll get your answer.
00:47
Now, if you can't remember this, another way to recall it is that if helium has an atomic mass of four, then this also means that there are four grams of helium per mole, and we can just convert this here to kilograms of a single molecule.
01:12
So to do that we remember that there are a thousand grams in one kilogram.
01:21
And then we'd also remember that there are 6 .023 times 10 of the 23rd items or molecules or atoms per mole...
