Question

How many moles are in 2.06 x 1022 molecules of an unknown compound?

Answer 1

In order to answer that we will use the Avogadro's number, which is the constant number that represents 1 mol, this value is equal to 6.02*10^23 atoms or molecules

6.02*10^23 = 1 mol

2.06*10^22 = x moles

x = 0.03 moles of an unknown compound
