Jul 22nd, 2015

Thank you for the opportunity to help you with your question!

1 mole of C6H6 =6.02214 *10 ^23 molecules

1.300*10^-2 mole of C6H6=x molecules

x=6.02214*1.300*10^-2 *10^23

  =7.828 *10 ^21 molecules

Please let me know if you need any clarification. I'm always happy to answer your questions.
