Question
Hydrogen gas can be produced by reacting aluminum with sulfuric acid. How many moles of sulfuric acid are needed to completely react with 15.0 mol of aluminum?
2Al(s) + 3H2SO4(aq) Al2(SO4)3(aq) + 3H2(g)
2Al(s) + 3H2SO4(aq) Al2(SO4)3(aq) + 3H2(g)

the equation says that for every 2 moles of Al, you need 3 moles of H2SO4.
So, you will need 3/2 * 15 = 22.5 moles of H2SO4
So, you will need 3/2 * 15 = 22.5 moles of H2SO4
