Question

Which equivalence factor set should you use to convert 126 g C to atoms C?
Pick One:
a. (1 mol C/126 g C)(6.02 x 1023 atoms C/1 mol C)
b. (1 mol C/12.01 g C)(6.02 x 1023 atoms C/1 mol C)
c. (12.01 g C/1 mol C)(1 mol C/6.02 x 1023 atoms C)
d. (12.01 g C/1 mol C)(6.02 x 1023 atoms C/1 mol C)

Answer 1

Hmm i actually just did this in class too so im trying to work it out as to not give you a wrong answer

Answer 2

I think we need to convert to moles by dividing the number of grams by Avogadro's number.
And then multiplying that by something.
I think it might be c or d? hmm...
any thoughts?

Answer 3

I believe your answer would be A because the way it is set up, mols would cancel out and you would be left with the number of atoms

Answer 4

Hang on

Answer 5

hahaha this question has had me stumped for almost ten minutes. ugh.

Answer 6

This is how it would have to be done to go from mass to atoms

Answer 7

(grams) x (6.02 x 10^23) / (mass of the element in grams)

Answer 8

but that doesnt look like any of those =/

Answer 9

Oh I see! So what I had suggested earlier was wrong. It needs to be from grams to atoms.

Answer 10

Well, I think I'll try to google the answer. hahaha.

Answer 11

Alright but I'm pretty sure you were right about c or d

Answer 12

Google failed me... :(

Answer 13

If you have to guess, go with c. It makes sense that 12.01 is 1 mol, times 1 mol which is 6.02 x 10^23 atoms

Answer 14

so everything cancels out and you're left with atoms

Answer 15

Alright! C it is! In fact, now that you just said that it looks to me as if C is the right answer! You are a saint!

Answer 16

Haha alright, hopefully you got it
