Use the ideal gas equation, and the volume above, to calculate the number of moles of H2 gas produced during each unknown run. Assume again that the gas temperature at the end of each run is 22 degrees C.
Hint from teacher: Use the formula PV=nRT to solve for n (number of moles). You know the volume, or "V" (calculated in discussion #22), you know the value of R (0.0821 L x atm/mol x K). Make sure you convert the temperature to Kelvin and the pressure to atm before plugging into this formula.
Volume is 24.216 Litres from #22
