Dear Student,
Please see to the solution and If there are any doubts or need further explanation,please feel free to comment here and may upvote if you understand the solution.
From the reaction,2 moles of H2 will react with 1 mole of O2 TO GIVE 2 MOLES OF H2O.
Here in the given question H2 is 31.78 mol and O2 is 2.64 mol.As per the equation 1 mole of O2 needs two moles of H2 and Oxygen is limted and Hydrogen is excessive(Therefore limiting reagent is Oxygen).
1 mole of O2 reacts with 2 moles of H2 and produces 2 moles of H2O
2.64 mol of O2 reacts with 5.28 moles of H2 and produces 5.28 moles of H2O.
1 mole of H2O is 18 gm
5.28 moles of H2O is 95.04 grams and as per the options,THE NEAREST ANSWER WOULD BE option (D)
