Calculate the amount of gas produced when collected by water displacement. Aluminum reacts with aqueous sodium hydroxide to produce hydrogen gas: 2Al(s) + 2NaOH(aq) + 6H2O(1) 2NaAl(OH)4(aq) + 3H2(g) In one experiment, a sample of Al reacts and the gas produced is collected by water displacement. The gas sample has a temperature of 23.00 °C, a volume of 860.0 mL, and a pressure of 747.0 mm Hg. Calculate the amount (in moles) of hydrogen gas produced in the reaction. The...
