On the same subject as before with the limiting/excess reagent stuff -- can someone please check my answer to make sure I'm doing it right? Thanks sooooo much!! :DD

3. Mg + 2HCl ==> MgCl2 + H2 -- What mass of hydrogen at STP is produced from the reaction of 50 g of Mg and the equivalent of 75 g of HCl?

==> I got about 2.08 g H2.

4. How much of the excess reagent in Problem 3 is left over?

==> I got about 12 g Mg.

  • Honors Chemistry -

    Oops, I mean I got 49 g Mg for number 4.
