Avogadro constant question
« on: May 15, 2012, 04:54:47 PM »
Hi,

I had an exam today and one of the questions was: "There are 0.0120 mol of S8, how many particles are there," well something like this, I used avogadros constant, but was then told after the exam by a friend that you had to times the answer by 8, is that the case?

Are you sure question asked about particles? Not atoms or molecules?

Yeah you had to multiply by 8 if it wanted atoms because there are 8 S atoms per one molecule of S8.
