How many grams of co2 would be formed from 53.8 g of c2h6 and unlimited o2 in the reaction 2c2h6+7o2–> 6h2o+4co2

Answer : The mass of formed will be, 157.52 grams.

Solution : Given,

Mass of = 53.8 g

Molar mass of = 30 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 given balanced chemical reaction is,

From the balanced reaction, we conclude that

As, 2 moles of react to give 4 moles of

So, 1.79 moles of react to give moles of

Now we have to calculate the mass of .

Therefore, the mass of formed will be, 157.52 grams.
