The information we need from our periodic table of elements. Periodic table of elements, it has a molar mass ofġ6.00 grams per mole. Of 1.008 grams per mole, 008 grams per mole. Of 12.01 grams per mole and now we can think about

Mass of a carbon atom, or what's useful, and this is where Avogadro's Number is valuable, if you have Avogadro's Number of carbons, it is going to have a mass of 12.01 grams. We've talked about it in other videos, you could view this 12.01Īs a relative atomic mass of a carbon atom, of as the average atomic Periodic table of elements, has a molar mass of 12.01 grams per mole. So if we first look at carbon, carbon, we see from this So what is the molar mass of glucose? Well to figure that out, and that's why this periodic table of elements is useful, we just have to figure out the molar mass of the constituent elements. Well then we just divide the mass of our sampleīy the mass per mole and we'll know how many moles we have. And so we have a 1.52 kilograms sample of our molecule in question, of glucose so if we can figure out the mass per mole, or another way to think about it, the molar mass of glucose, If I say a mole of something, I'm saying that's Avogadro's If I said a dozen of something, you'd say oh, that's 12 of that thing. Remember, mole is really, you can view it as a Trying to figure out the number of moles, So like always, pause this video and try to figure this out on your own and this periodic table ofĮlements will prove useful. We are asked to calculate the number of moles in a 1.52
