Supplemental video explaining how to do molar conversion problems.

hey what's up this is kind of an extra does supplemental video you you don't just wants not a required video but this one will just give you a little extra to look at as far as I know Rosa you know that this is 27 is the number of protons atomic number if I were to say what is 8.9 grams you can also write her what's the molar mass of carbon is 12 cuz there's 12 grams in one mole carbon magnesium magnesium has a molar mass of 24.305 gram 24 in the way out in the reason I'm writing this is because that's really going to help you when we get to know how to set it up cuz you're going to set it up like that and work things out I'll go ahead and I'll write the answers in if you want to work things out then hit pause now because I'm about to put the answers on here go back we look at the rally and there's beryllium right Sunbury Daily Item is 9 grams per mole and 59 grams per supper would be 32 grams per mole Neon right here 20 grams per mole .96 72197 so gold is 197 grams per mole practice problems okay so now we're going to have to add different to have two number so sodium will just round 22.990 volume up to 23 23 for 7 a.m. and then we need chlorine with chlorine is 35.453 just keep that 135 2335 you have one sodium atom of the 130 mm in 1/4 inch 5 + 3 is 2 + 3 gram + go down here this right here really subscript and this too means that there's two hydrogen's we have this hydrogen is one gram so we would do One X two or one plus one anyway so each one G cell are hydrogen is going to be to grow for hydrogen if we go back and look it over here 16 + 2 1818 Graham let me go any race this in the middle so we'll have more room to work alright so we have to aluminum have a mass of 26.9 so we will do 2727 now there's two of them Al 203 which means 7 is 14 grams and then for oxygen grease all over here oxygen was 16 gram. then our oxygen is 48 grams 102 grams per mole and this is the hardest one erase all day what are elements Chopper we have nitrogen and we have oxygen this too has to be distributed to each other alright nitrogen there's no number here so we have one night but this to that is  so we have six does not go with that one of those so we can actually go by Friday 63.544 grams of copper if we go back we will get nitrogen nitrogen is 14 and 12 mm Turn Down for What oxygen oxygen 16 6:30 96 + 28 + 9 equals so once we get once we once we figured out what each of these with the masses of each of these are because we just favorited multiplied added it all up and then we add the three together we see that way 88 grams per mole what is the point of all of this you have to know how to do to be able to do molar convert these are really easy but I wanted to show you these just so that you can see how to set the stuff you watch the other video you know that the first thing you want to do when you convert grams in grams of 5 moles of silver the first thing you want to do is first right what you bought you know you already have 5 moles of silver and then we can go ahead and put a line going down the conversion table I need to get rid of moles is going to go down right and then there's will cancel out and add whatever I'm Converse all right you're converting to grab over here when you're right we have to what is the date that we can go ahead and say 108 set an alarm 108 grams per mole we have 5 months 1/8 * 5 equals 5 has a mass of 540 grams AG down here to indicate that were talking about myself from this phone is the same thing except we already are given we need to figure out how many moles how many moles the first thing you ride is what you already been getting what you already know you know that you have 75 grams of carbon you have and you're trying to get rid of Graham you want to cancel your grandpa or Grampa or you can think of it this way I'm converting to moles so mold need to go up top whatever goes up top one next to mole one mole is how many grams of carbon periodic table is always 12:12 one mole of carbon has a mass of 12 grams please cancel out and relax with no cuz that's what we're converting to everything was up top Auto Part straight across this one on the other hand and 12 is down here so in order to 75. 7 / 12 equals 6.256 moles of carbon then that is going to have a mess convert convert
