Correct Answer: Option A

Explanation

First, write a balanced chemical equation of the reaction:

         C\(_2\)H\(_5\)OH  +  3 O\(_2\)  → 2 CO\(_2\) + 3H\(_2\)O

                                3moles     :     2 moles

       Using  n = \(\frac{mass}{Molar mass}\), \(\frac{6}{32}\)          :  x mole

                                      0.1875 mole :  x mole

By simple proportion, X = \(\frac{0.1875  X   2}{3}\)

                                   X = 0.125 mole
