Potassium metal reacts vigorously when placed into a beaker of water. The reaction liberates so much heat that the hydrogen gas evolved often ignites, burning with a characteristic lilac flame. The equation for the reaction is 2K + 2(H2O) -> 2(KOH) + H2.
Calculate the mass of hydrogen gas that would be given off by the reaction of 3.91g of potassium metal in a beaker of water.
