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:
NaOH + Al + 6H2O  2NaAl(OH)4 + 3H2
What mass of aluminum would be needed to produce 4L of hydrogen gas at 101kPa and 25C?

What value of R is used when solving the PVnRT equation?
0.0821 L * atm /  mol *K
8.314 L *atm / mol *K
8.314 L * kPa / mol *K
R is not needed for this problem
