When active metals such as magnesium are immersed in acid solution, hydrogen gas is evolved. Calculate the volume(in L) of H2(g) at 35.2°C and 646 torr that can be formed when 325 mL of 0.855 M HCl solution reacts with excess Mg to give hydrogen gas and aqueous magnesium chloride.
Mg(s) + HCl(aq) --> MgCl2(aq) + H2(g) (unbalanced)
