Fa sample of butene (c4h8) that has a mass of 136.6 g is combusted in excess oxygen, what is the mass of co2 that is produced?

c4h8 + 6 o2 --> 4 co2 + 4 h2o

Answer : The mass of produced will be, 429.264 grams

Explanation : Given,

Mass of = 136.6 g

Molar mass of = 56 g/mole

Molar mass of = 44 g/mole

First we have to calculate the moles of .

Now we have to calculate the moles of .

The balanced chemical reaction is,

From the balanced reaction we conclude that

As, 1 mole of react to give 4 moles of

So, 2.439 moles of react to give moles of

Now we have to calculate the mass of .

Therefore, the mass of produced will be, 429.264 grams.

since electrons are negative the answer is neagtaive
