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.
