See below

Explanation:

#Mg(s)+2HCl(aq)-> MgCl_2(aq)+H_2(g)#

I'm gonna assume room temperature to be the standard thermodynamic temperature:

#0.24cancel" g Mg"xx(1cancel" mol Mg")/(24.31cancel" g Mg")xx(1cancel" mol H"_2)/(1cancel" mol "Mg)xx (0.082 "L"cancel"atm")/(cancel"mol K")xx(298 cancel"K")/(1cancel "atm")= 0.24" L ""H"_2#
