Question

How many molecules of SF6 are in 81 moles

Answer 1

= 4.9 x 10^25 molecules of SF6

Step-by-step explanation:

There's a guy named Avogadro something who said 1 mole of anything has 6.022x10^23 units (such as molecules, ions etc.) of that thing.

So to get to molecules just multiply 81 moles by 6.022x10^23

= 4.9 x 10^25 molecules of SF6
