How many moles of chlorine are in 6.67x10^40 chlorine molecules put in scientific notation

To solve for the number of moles, we simply have to use the Avogadros number which states that there are 6.022 x 10^23 molecules per mole. Therefore:

number of moles = 6.67 X 10^40 chlorine molecules / (6.022 x 10^23 molecules / mole)

number of moles = 1.108 x 10^17 moles
