How many carbon atoms are there in a diamond (pure carbon) with a mass of 50 ?
Answered by Damon
grams? kilograms ? Carats ?

If grams (pretty big)

6*10^23 carbon atoms weigh 12 grams
so
50 grams * 6*10^23 / 12 = 25*10^23 = 2.5*10^24 atoms

It's 50mg. I really don't understand how to do this.
Answered by Damon
It is milligrams, so divide by 1000
Answered by Damon
The atomic weight in grams is the mass of 6*10^23 atoms (Avagadro's number)
