 so the time of it is really sure I think I think that you know we these days people need it like so small to be digestible or you know they'll lose their interest there's something really quick yeah so that's why I'm doing one problem one problem one problem you know yeah yeah it's almost better than some people all of them be that for them yeah and they'll be like oh I have to sit there are three these three problems to do this okay so let's do this next one one million argon atoms is blank moles of argon atoms okay so you know already right what how many one mole is right how many things one mole is how many is that talking about the I've got his number you're 6.00 to 222 222 23 remember I told you that's just it's just like saying if you think think of this is like to chemistry then you're losing the battle with chemistry you know what I'm saying it's like you saying like doesn't only is talking about donuts I cannot apply that to eggs you know what I'm saying yes so I can have a dozen eggs I can have a dozen donuts I can have a mole of donuts eggs anything so okay so this is just whatever items you know it's just one big number yeah it's just a huge frickin number you know that's it in this case since we're talking about argon atoms what we really should write just to be not confusing is to say one mole of argon atoms right equals 6.0 222 times 10 to the 23rd argon atoms does that make sense okay so that's the best way to and then we know it says one million argon atoms is the number that we have so the number we have of argon atoms is one million so one that's written now so what is that I guess they want this to two sig figs okay so whatever only reason I know that is because we've got a number of argon atoms and we've got a way to convert that number to moles so that's all we need to do you know so how many moles do we got moles okay so we go one mole so our one million and you want to get argon atoms out of there right so one mole of argon atoms equals 6.0 222 times 10 to the 23rd argon atoms argon atoms cancel out and you're left with moles of argon atoms all you got to do is so would you expect this to be a number smaller or bigger than one just looking at it straight away so this is like 1.0 times 10 to the 6 right this is 1.0 times 10 to the 23rd it's gonna be bigger right well is this so this is dividing by this one this one's big and this one's small so that's like saying a small number divided by a big number is that bigger or smaller than one that's bigger this number is bigger or smaller than one no that's smaller okay I'm not don't make me get my orders out again okay so whenever you see a big number divided our small number divided by a big number right this is much bigger than this right this is six this is 23 right it's gonna be less than one okay so if your answer isn't less than one you've done something wrong okay so that makes sense okay so one million she wanted to do 100,000 divided by we stick it with three six fix let's see the answer is gonna be in two six six yeah that's the so our options are either one or two six fix and I from the answers I would assume that it's going to be 1.7 times 10 to the negative 18 yes are gone are yeah all those is that numbers bigger smaller than one that's smaller how do you know that negative on the 18 so you want to always check yourself right before you go on to the next problem so if you get something that's like to the 23rd or something like that doesn't make any sense you know this isn't even one mole right yes one mole is this many you know so this is 1.0 times 10 to the 6 that's not that many right that's not even close you still got to multiply that by almost four to get that right yeah okay so you want to think about it that way go with that one
