Oh honey, let me break it down for you. Avogadro's number tells us that 1 mole is equal to 6.022 x 10^23 atoms. So, to find out how many moles are in 1.25 x 10^25 atoms of phosphorus, you just need to divide the number of atoms by Avogadro's number. That gives you approximately 20.75 moles of phosphorus.
