Some commercial drain cleaners contain two components: sodium hydroxide and aluminum powder and undergo the following reaction:
2NaOH(aq) + 2Al(s) + 6H2O(l) → 2NaAl(OH)4 (aq) + 3H2(g) in the presence of water (for H2, the van der Waals constants are a=0.244 atm*L2/mol2 and b=.0266 L/mol). Assuming the reaction is done in a 2.0 L container at 300 K:
a) What is the pressure of H2 (assuming H2 is an ideal gas) when 6.0 g of Al is treated with excess NaOH
b) What is the pressure of H2 (assuming H2 is a nonideal/real gas) when 6.0 g of Al is treated with excess NaOH

Collecting Gas over Water
Aluminum reacts with aqueous sodium hydroxide to produce hydrogen gas according to the following equation: 2Al(s) + 2NaOH(aq) + 6H2O(1)—>2NaAl(OH)4(aq) + 3H2(g) The product gas, H2, is collected over water at a temperature of 20 °C and a pressure of 756 mm Hg. If the wet H2 gas formed occupies a volume of 5.83 L, the number of moles of Al reacted was mol. The vapor pressure of water is 17.5 mm Hg at 20 °C.
