Can someone please help me with this chemistry question..

Hydrogen gas can be produced by reacting aluminum with sulfuric acid. How many moles are needed to completely react with 15.0 mol. of aluminum?
2Al(s)+3H2So4(aq) --> Al2(SO4)3 (aq) +3H2(g)
A. 0.100 Mol
B, 10.0 Mol.
C 15.0 Mol
D 22.5 Mol

2 Al + 3 H2SO4 → Al2(SO4)3 + 3 H2

(15.0 mol Al) x (3/2) = 22.5 mol H2SO4
