Give the theoretical yield, in grams, of co2 from the reaction of 4.000 moles of c8h18 with 4.000 moles of 02 2 c8h18 25 02 16 co2+ 18 h20

Answer : The theoretical yield of is, 112.64 grams.

Explanation : Given,

Given moles of = 4 moles

Given moles of = 4 moles

Molar mass of = 44 g/mole

First we have to calculate the limiting and excess reagent.

The balanced chemical reaction is,

From the given balanced reaction, we conclude that

As, 25 moles of react with 2 moles of

So, 4 moles of react with moles of

From this we conclude that, is an excess reagent because the given moles are greater than the required moles and is a limiting reagent because it limits the formation of product.

Now we have to calculate the moles of .

As, 25 moles of react to give 16 moles of

So, 4 moles of react to give moles of

Now we have to calculate the mass of .

Therefore, the theoretical yield of is, 112.64 grams.

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)

i'm assuming that it's c.) red bank..
