Title: Find mole of element in (nh4)3po4
Post by: plantguy126 on March 30, 2019, 09:59:28 PM

Hey,
How would you go about finding the mole of phosphorus atoms in 2 moles of (NH4)3PO4?
Thanks

Think of a mole as if it was an overgrown dozen. Dozen has 12 elements, mole 6.02214076×10²³ elements, otherwise they aren't much different.

How many phosphorus atoms in a dozen molecules of (NH₄)₃PO₄? How many dozens of atoms is that?
