One mole of Benzene = 6.0221415 × 10^23 molecules
sample has 7.61 x 10^24 molecules of benzene
Moles of benzene = 7.61 x 10^24 / 6.0221415 × 10^23
= 12.637 moles

1 mole of element contain 6 x 10^23 of particles(avogadro's constant)
note that the type of particles must be included like atom,molecules or ions
since a sample of benzene contaiins 7.61 x 10^24 molecules
then....the number of moles of benzene is( 7.61 x 10^24 divide by avogadro's constant)
just do the math....

(7.61*10^24)/(6.023*10^23) i think.
12.63 moles
