What is the number of moles of chemical units represented by 9.03x10^24?

To determine the number of moles of given number of particles, we need a conversion factor to multiply or divide to the given value. For this case, we use the Avogadro's number. It represents the number of units in one mole of any substance. This has the value of 6.022 x 10^23 units / mole. This number can be used to convert the number of atoms or molecules into number of moles or vice versa. We do as follows:

9.03 x 10^24 chemical units (1 mol / 6.022x10^23 chemical units) = 14.9950 moles

Therefore, 9.03 x 10^24 chemical units represent about 15 moles.
