Avogadro's number
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.
11.8 g ( 1 mol / 95.21 g ) ( 6.022 x 10^23 formula units / mol ) = 7.46 x10^22 formula units
Hope this answers the question. Have a nice day.
