How many atoms of Al
are needed to react with
34.5 grams of O2 gas?
4Al + 3O2 → 2Al2O3

What is the question

Your question is not clear but if you can explain yourself i would be glad to .  just trying to : ))

Hello! data: p (pressure) = 1.25 atmv (volume) = ? (in l)t (temperature) = 298 kn (number of mols) = 0.900 molesr (gas constant) = 0.082 (atm*l/mol*k)apply the data to the clapeyron equation (ideal gas equation), see: i hope this . =)
