What mass of PbCl2 contains 1.0 x 1024 atoms of Cl?
Can someone help me get this one started?

Well I found something in my old chemistry copybook..
So i think this is what you have to do..
divide 1024 by Avogadro's number..you will get the number of moles, then easily you can find the mass!:)
I hope I'm right, and it helps!
Good Luck:)
