Aluminum granules are a component of some drain cleaners because they react with sodium hydroxide to release both energy and gas bubbles to help clear the drain clog. The reaction is:

2NaOH + Al + 6H2O  2NaAl(OH)4 + 3H2
(note: balance the reaction first)

What mass of Aluminum would be needed to produce 4L of hydrogen gas at STP?
