Question

What is the molar mass of 1-butene if 5.38 × 10^16 molecules of 1-butene weigh 5.00 μg?

Answer 1

Make a ratio: \(\sf \dfrac{mass~of~sample}{\#~of~molecules}=\dfrac{Molar~mass}{Avogadro's~\#}\)

Answer 2

@aaronq
Is it okey if you explain it by number? :)

Answer 3

explain by number? what do you mean?

Answer 4

@aaronq
Sorry English not my native language
I mean like that
5.00/5.38*10^1......

Answer 5

so 5.00 \(\mu g\)/(5.38 × 10^16 molecules)=molar mass/(6.022*10^23)

Answer 6

@aaronq
Thanks :)

Answer 7

no problem
