If the molar mass of hydrogen is 1.008 g/mol, what is the mass (in grams) of 2 hydrogen atoms?

Alright, everyone. So here's a practice problem. Hopefully, you're able to figure out on your own, but if not, here's a little bit of help. In this problem, we're supposed to calculate the mass in grams of 2 hydrogen atoms. So when we look at all of our equations here, on this little flowchart, we know that we have number of particles, moles, and mass. The variable that we're looking for is this little m over here. So the equation we're gonna start with is this one. So let's go ahead and get started here. We have n equals little m over big M. Now what we're looking for here is this little m, that's the mass. So we're just gonna move everything over to the other side. So I'm just gonna move this big M over to the other side and what I get is n times big M is equal to m. Right? So I need the number of moles, that's this m, and then I need the grams per mole, and when I multiply that I just get mass. Now the good news is I have what the molar mass is and I'm giving it in terms of grams per mole that's hydrogen. So you remember you can always get this from a periodic table. It's just that number, that's gonna be the atomic mass there. So that's the grams per mole. Alright? So unfortunately though we don't know how many moles we're dealing with. All we know is that we have to find the mass of 2 hydrogen atoms. So remember if you're missing n you can always get that from the other equation by relating the number of particles to the number of moles. That's the sort of other equation that we have. So basically what we need to do here is we just need to go and use this equation to figure out the number of moles. So we're just gonna kinda go to the left here, but, you know, kind of makes sense according to our flowchart. So we have big N divided by this n a. Remember this n a here is Avogadro's number. I've listed it there just in case you forget. Now what we have here is we have 2 particles and then divided by 6.022 times 10 to the 23rd, and remember this is particles per mole. Right? So what happens is we have 2 particles and when the, when you do this out when you work this out you're gonna get 3.32 times 10 to the minus 24 and that's the number of moles. So that's actually what goes inside of this number over here. So I'm gonna kinda move this over, so we can sort of drop this down a little bit. Right? So now all we have to do is now that we have n, we just need to multiply this out. So this is gonna be 3.32 times 10 to the minus 24 and that's moles, and then we can multiply by the molar mass. Now because all of our answer choices are in grams, we don't have to convert the 1.008, but if all of them were in kilograms, you would have to convert it. Okay? So we can just leave this as 1.008, and I always encourage you to just leave the unit so you can know and be sure that everything checks out. Right? So this is grams per mole. So what happens is the moles is gonna cancel out and you'll just end up with grams, which is exactly what you want. Now when you work this out basically what you end up with is 3.35 times 10 to the minus 24 and that's gonna be in grams. Alright. So that's your final answer. When you go through your answer choices, this is gonna be answer choice b. Alright. So let me know if you have any questions about
