Mg(s) + 2HCl(aq) --> MgCl2(aq) + H2(g)
If 1.0g of Mg is reacted with 10.0mL of 6.0M HCl, what volume of hydrogen gas will be produced at 298K & 1atm?
This is a limiting reagent problem; I know that because an amount for BOTH reactants is given. I solve these problems by working TWO simple stoichiometry problems (simple meaning not limiting reagent) for the amount of a product formed. Of course this will produce different answers but the correct value in limiting reagent problems is ALWAYS the smaller one. Here is a link to solving simple stoichiometry problems.
Post your work if you get stuck.
