Identify how many moles are in 3.01 x 10 exp 21 molecules

There are 0.005 mol in that amount of molecules.

Step-by-step explanation:

A mol has 6.02*10^ (23) molecules, therefore in order to calculate the number of moles that are in 3.01*10^ (21) molecules, we need to divide it by the number of one mol. This is done below:

number of moles = number of molecules / 6.02*10^ (23)

number of moles = 3.01*10^ (21) / 6.02*10^ (23)

number of moles = 0.5*10^ (21 - 23)

number of moles = 0.5*10^ (-2) = 0.005 mol

There are 0.005 mol in that amount of molecules.
