1 mole of any gas takes 22.4 L.
1 dm3 = 1 L
1 cm3 = 0.001 L

a million.2 mol al / (3 mol H2 / 2 mol Al) <--- mole ratio for stoich. = a million.8 mol H2 STP = a million atm and 273 ok R continuously = 0.0821 (l atm / mol ok) Pv=nrt (desirable gas equation) Plug and chug. a million atm (X) = a million.8 mol H2 x (0.0821 L atm / mol ok) x 273 ok = 40.34 L (in keeping with sig figs)

I took that last semester....
n = PV/RT
where: P=pressure, V=volume, n=number or moles, R=is a constant, and T= Temprature in Kelvin....
STP: is when you have room temp (25 deg. Celsius, and 1 atmosphere pressure.) I'm not sure what R is look it up...probably...8.26....
do the rest yourself
