# Problem: A mixture of C3H8 and C2H2 has a mass of 2.6 g. It is burned in excess O2 to form a mixture of water and carbon dioxide that contains 1.6 times as many moles of CO2 as of water.Find the mass of C2H2 in the original mixture.

###### FREE Expert Solution

The balanced combustion reaction of both reactants are shown below:

Now we have to establish an equation based on the sum of the mass of C3H8 and C2H2 equal to the mass of the mixture.
