What was the reaction?


Dihydrogen gas could be a product of alkali metal reduction:

#Na(s) + H_2O(l) rarr NaOH(aq) + H_2(g)#

Unless you specify from what reagent the gas was formed we cannot help you. Note that #250*g# is a very large molar quantity of dihydrogen gas, and it would occupy a lot of volume under standard conditions.
