How many moles of co2 are produced when 45.0g of c6h6 react completely in the following equation? 2c6h6+ 15o2 → 12co2 + 6h2o

Answer : The moles of produced are, 3.462 moles.

Explanation : given,

Mass of = 45.0 g

Molar mass of = 78 g/mole

First we have to calculate the moles of .

Now we have to calculate the moles of

The given balanced chemical reaction is,

From the balanced chemical reaction, we conclude that

As, 2 moles of react to give 12 moles of .

So, 0.577 moles of react to give moles of .

Therefore, the moles of produced are, 3.462 moles.

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"
