Zn + 2HCl -> H2 + ZnCl2
molar mass of Zn is 65.39 g/mole
molar mass of H2 is 2.02 g/mole
How many grams of hydrogen are produced when 15 grams of Zn are used?
The answer I keep getting is .46 grams of H2
I do not know if that is right

You are correct, because you would set the problem up like this..
15 G zn /1 x 1 mol zn /65.39g zn x 2.02 g H2/1mol zn
The Grams of zn would cancel as well as the moles of zn. You would multiple the top and divide by the bottom, getting you .46 g of H2.
PLEASE answer my question!

15 grams zinc x (1 mol zinc)/(65.39 grams) = .229 mols of zinc
.229 mol zn x 1 mol H2/1 mol zn x 2.02 grams/ 1 mole H2 = .463
You are correct
.229 mol zn x 1 mol H2/1 mol zn x 2.02 grams/ 1 mole H2 = .463
You are correct
