What are the number of molecules in 1.300 10-2 mol C6H6 ?
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
=7.828 *10 ^21 molecules
Thanks how do i write that with e? is it 7.829e+21 or 7.829e21?
7.829e21 should be correct.
Thank you so much!
