What volume of H2 is produced if excess nitric acid (HNO3) reacts with 46.3 g of magnesium

2HNO3 + Mg → H2 + Mg(NO3)2

mols Mg = grams Mg/atomic mass Mg = ?

Using the coefficients in the balanced equation, convert mols Mg to mols H2.
Now convert mols H2 to volume (in L) knowing that 1 mol will occupy 22.4 L.
