I am not sure if the equivalents of $\ce{H2}$ in the equation $$\ce{Mg (s) + 2HCl (aq) -> MgCl2 (aq) + H2}$$
is that of dry or wet hydrogen.

If the $\ce{H2}$ refers to wet hydrogen in the equation, how should I find the volume of dry hydrogen given the pressure of wet and dry hydrogen and the volume of wet hydrogen?

    $\begingroup$ The water is a liquid. It exerts a vapor pressure. Some of the pressure in the gas is not due to hydrogen, it is due to water vapor so it is called wet hydrogen. $\endgroup$
