Question

I need help setting up this problem: A 5.0 sample of O2 is in a container at STP. What volume is the container and how many molecules of O2 in the container and how many atoms of oxygen?

Well, 5.0 grams?

PV=nRT
You are given STP conditions, so that gives pressure and temp.
n= grams/32
solve for V

how many molecules: n*avagnumber.
