Question

brrr

Answer 1

the third one (1 mol O2/6.02 x 10^23 molecules O2). because there are 6.02 x 10^23 molecules in 1 mole of a substance.

Answer 2

Which equivalence factor should you use to convert from 6.26 moles of O2 to molecules of O2?


(1 molecule/6.02 x 10^23 mol O2)

(6.02 x 10^23 molecules O2/1 mol O2)

(6.02 x 10^23 molecules O2/6.26 mol O2)

(6.26 mol O2/6.02 x 10^23 molecules O2) <----?

Answer 3

I did the formula

Answer 4

yes you got it right

Answer 5

To your second question: (6.02 x 10^23 molecules O2/1 mol O2) is the answer because of the mole ratio. From your first question, you use the ration to go from molecules to moles. To reverse it, you multiply by the reciprocal.

Answer 6

Oh okay
