 Okay, let's try this one now. So Let's figure out how much one mole of carbon well place So in order to do this, it's just the next in a series of Well, you have to do a series of these conversion factors So, you know the mass of carbon 12, right? So the mass of Carbon is going to be 12 point Oh And you also know that one Dalton equals 1.661 times 10 to the negative 24th grain the mass of One atom of carbon 12. So you've also got another conversion factor, right? So the 12 12.0022 times 10 to the 23rd of the carbon 12 interesting So let's do that 12 618-24 Okay, so we've got that's how many grams one carbon 12 weighs 1.9932 times 10 to the negative 23rd grams and Then we just multiply that number by Avogadro's number to figure out how much a mole weighs In grains and notice we go to four significant figures So hopefully you guys see something interesting, right? So one mole of carbon 12 Right, this is the cool thing about Avogadro's number or the number one mole is that one mole of anything weighs the same mass in Grants per mole as one atom or one molecule did in Dalton so 12 Dalton's per atom of carbon 12 is 12 grams per mole and if you wanted to Okay, so it's a quick conversion factor that you shouldn't be able to use now So try some on the on your own very important that you understand this
