How many moles of nitrogen atoms are combined with 8.6 moles of oxygen atoms in dinitrogen pentoxide?
The formula is N2O5, which means that there are two nitrogen atoms for every five oxygen atoms. So if we have 8.6 moles of oxygen atoms, we have 2/5 as many moles of nitrogen atoms, or 3.44 moles of nitrogen atoms. For n moles of nitrogen and 8.6 moles of oxygen, we can set up the proportion: 8.6/5 = n/2. Solve for n and find n = 3.44 moles of nitrogen atoms.
