Answer: 10.84 moles of
will be produced from complete combustion of 5.42 moles of ethanol

Step-by-step explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number
6.023* 10^(23) of particles.

$2C_2H_6O+7O_2\rightarrow 4CO_2+6H_2O$

According to stoichiometry :

2 moles of ethanol produce = 4 moles of
CO_2

Thus 5.42 moles of ethanol will produce=
(4)/(2)* 5.42=10.84moles of
CO_2

Thus 10.84 moles of
will be produced from complete combustion of 5.42 moles of ethanol
