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. We calculate as follows:
19.2 x 10^23 molecules of AgNO3 ( 1 mol / 6.022 x 10^23 molecules ) (169.87 g/mol) = 541.60 g AgNO3
