Calculate the number of moles of H2SO4 required to react with 66.33 moles of Al. Do not include units in your answer. Round to the tenths place or further.

99.5 moles

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
