If 56.1 L of chlorine and 72.4 L of hydrogen are mixed, what volume of product will form at S.T.P.?

Is this a limiting/excess reagent problem? Do I have to do: 56.1/44.8 and then 72.4/22.4 and cross out the lower of the 2 or something first? I totally forget how to do this kind of problem

Thanks ppl
