Thread: Chem. Help

Could someone help me out with the following?


Consider the representation of a mixture below. If each circle represents 1.86x1022 atoms, how many moles of water molecules are in the mixture?

(imagine that there are 9 oxygen "circles" and 12 hydrogen circles)

you will have to use Avogadro's Number:
6.0221415 × 10^23 atoms or molecules / mol

I would say that he will have to use Avogadro's constant (because Avogadro's number has no units).

Best regards,

César
