  • when do i use the avogadros number? I thought that( 4.5*10^24)(1mol C/6.02*10^23 C atom)(6electron/1mol C) In Kyung commented over 1 year ago
  • Hey there! Take not that there are 6 electrons in a neutral carbon atom (1 C atom). The given is already in atoms of carbon. We only use the Avogadro's number when we need to convert moles to atoms. I hope this clears things up! Anne commented over 1 year ago
