Question

Which equivalence factor should you use to convert from 4.28 x 1019 molecules of O2 to moles of O2?


(1 mol O^2/4.28 x 10^19 molecules O^2)

(4.28 x 10^19 molecules O2/1 mol O^2)

(1 mol O^2/6.02 x 10^23 molecules O^2)

(6.02 x 10^23 molecules O2/1 mol O^2)

Answer 1

n=N/L
n - moles
N - number of molecules
L - avogadro's constant

Answer 2

(1 mol O^2/6.02 x 10^23 molecules O^2)?

Answer 3

is my answer correct or wrong :/
