    Is that an m or an M? I will assume you made a typo or didn't know any better and you meant M. Also, I assume you meant at STP.
    28.5L H2 x (1 mole/22.4 L) = ?? moles H2.
    moles HCl = ??moles H2 x (2 moles HCl/1 mole H2) = xx moles HCl.
    M HCl = moles/liters HCl.
    You know M and moles, solve for liters HCl
