5 moles of Al2O3 are reacted with 10 moles H2SO4, how many moles

5 moles of Al2O3 are reacted with 10 moles H2SO4, how many moles of Al2(SO4)3 will produce?

A. 3.33

B. 10

C. 30

D. 33.3

I got this question during a job interview.

The query is from Stoichiometry Applications Terminology in chapter The Chemical Reaction Equation & Stoichometry, Material Balances for Processes Involving Reaction and Multiple Units of Basic Chemical Engineering

Correct option is A. 3.33

Explanation: The balanced chemical reaction is Al2O3 + 3H2SO4 -> Al2(SO4)3 + 3H2O, =>  moles of Al2(SO4)3 = 10/3 = 3.33.
