Answer:
99.5 moles
Step-by-step explanation:
The reaction equation is;
2Al(s) + 3H2SO4(aq) ----------> Al2(SO4)3(aq) + 3H2(g)
From the balanced reaction equation;
2 moles of aluminium reacts with 3 moles of acid
Therefore 66.3 moles of Al reacts with x moles of acid
66.3 * 3 = 2x
x = 99.45 moles
x = 99.5 moles
