Question

Convert 4.50 moles of Fe to atoms of Fe

Answer 1

I have my periodic table so if there's a number that you need from there, let me know. And can you pleasee explain how you do it because I have others like that and I dont know how to do any of them

Answer 2

for this problem you do not need a periodic table, simply, you have to know what avogadros number is and what it represents. do you know?

Answer 3

Isn't it 6.022 times 10^23?

Answer 4

And that is the number of "things" in a mole

Answer 5

okay good, so if you have 4.5 "number" of things (moles).. how many atoms do you have?

Answer 6

I dont know.. I get confused after that

Answer 7

wait do you multiply the numbers? wait no. You cant cause that would be too big.

Answer 8

lol no you're correct. it's like if you had 4.5 dozens.. how many atoms do you have? 4.5 x 12, right?

same thing you have 4.5 moles, you have 4.5 x 6.023x10^23 atoms

Answer 9

it seems like a lot but this is because they're sooo small

Answer 10

so do you leave it as 4.5 x 6.023x10^23? or would I multiply that out?

Answer 11

multiply it out, keep it in scientific notation, obviously lol, or it won't fit on your page
