Answer:

A) 12 mol H2O.

Step-by-step explanation:

Hello,

In this case, for the given reaction:

$2C_2H_6+7O_2\rightarrow 4CO_2 + 6 H_2O$

We notice that oxygen is in a 7:6 molar relationship with water, for that reason, the resulting moles of water turn out:

$n_(H_2O)=14molO_2*(6molH_2O)/(7molO_2) \\\\n_(H_2O)=12molH_2O$

Thus, the answer is A) 12 mol H2O.

Best regards.
