The drain cleaner, Drainex contains small bits of aluminum which react with caustic soda to produce dihydrogen. What volume of dihydrogen at and one bar will be released when  of aluminum reacts?

Solution: The balanced chemical equation is .
54 g (2 mol) of Al will give 3 moles (or 67.2 L) of hydrogen.
0.15 g of Al will give of hydrogen.
The volume of hydrogen is at 1 bar and 273 K. The volume at 1 bar and will be, .
