Question

Which equivalence factor should you use to convert from 6.26 moles of O2 to molecules of O2?
(Points : 3)

(1 molecule/6.02 x 1023 mol O2)


(6.02 x 1023 molecules O2/1 mol O2)


(6.02 x 1023 molecules O2/6.26 mol O2)


(6.26 mol O2/6.02 x 1023 molecules O2)

Again, I believe it is the 4th!

Answer 1

Molecules /6.02x10^23=moles
moles*6.02x10^23=molecules

Answer 2

The third one? And I did work on it, but that response was totally helpful!

Answer 3

it should be 6.26 *6.02x10^23

Answer 4

That isn't an option...

Answer 5

Weird !

Answer 6

I mean you seem like you know what you are doing... could it be the teacher made a mistake?

Answer 7

Its a basic rule .. !
I'am sure of this rule though

Answer 8

Well,It is a basic rule as i said
Maybe there is a trick somewhere ,ugh i'm kinda tired to notice xD

Answer 9

I think a chemistry TEACHER should know the basic rules of what they are TEACHING.

Answer 10

\(6.26 \text{ mol } \text O_2\)
\[=6.26 \text{ mol } \text O_2\times6.02\times10^{23}\frac{\text{molecules}}{\text{mol}}\]\[=(6.26\times 6.02)\times10^{23} \text{molecules } \text O_2\]\[\approx 3.8\times10^{24} \text{molecules } \text O_2\]

Answer 11

we have multiplied the quantity of gas by the second option

Answer 12

Your answer doesn't match any of the choices given... it matches what the other person said

Answer 13

option 2

Answer 14

Which equivalence factor should you use to convert from
\(\color{teal}{6.26\text{ moles of O}_2}\) to \(\color{brown}{\text{molecules of O}_2}\)?

\[\color{red}{(6.02 \times 10^{23} \text{molecules O}_2/1 \text{ mol O}_2)}\]


\(\color{teal}{6.26 \text{ mol O}_2}\) x \(\color{red}{(6.02 \times 10^{23} \text{molecules O}_2/\text{mol O}_2)}\)

= 3.8e24\(\color{brown}{\text{ molecules of O}_2}\)

Answer 15

OHHH! That makes total sense now! I was looking at it like what "factor set" instead of the proper set-up.

Answer 16

Unkle is right again!!!
