This video, we're gonna go over how to convert grams to moles.
00:07
For this example, we're use calcium, which has an atomic mass of 40.7 this is a readily available number find on periodic tables, george, with a quick google, we're also going to say that we have 77.4 grams of calcium.
00:27
We're gonna see how many moles of calcium we have.
00:32
So our first step in this problem is to get rid of grams, get rid of grams when multiplying by 77.4 grams.
00:42
We know we need multiplied by something as grams on the bottom.
00:46
We're gonna use our atomic mass in this example because we know that one mole of calcium is equal to 40.78 grams of calcium.
00:55
So in this equation, we can put one mole of calcium over 40.78 grams of calcium...
