C3H8 + 5O2 → 3CO2+ 4H2O, if 5.75L of oxygen are consumed in the above reaction, how many L of carbon dioxide are produced?

3.45 L carbon dioxide are produced

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number of particles.

To calculate the moles, we use the equation:

According to stoichiometry :

5 moles of produce =  3 moles of

Thus 0.257 moles of will produce=  of  

Volume of

Thus 3.45 L carbon dioxide are produced

the answer to this question is 3.
