# Ethylene gas burns in air according to equation C2H4(g) + 3O2(g) 2CO2(g)+2H2(l) If 13.8 L of C2H4 at 21 ˚ C and 1.083 atm burns completely in oxygen, calculate the volume of CO2 produced, assuming the CO2 is measured at 44 ˚ C at 0.989 atm?

##### 1 Answer

32.53 L of

#### Explanation:

Treating the gases involved in this reaction as ideal gases means we can solve this problem using the Ideal Gas Law

Where

First calculate the number of moles of ethylene gas we are burning by rearranging the ideal gas law for n:

We need to convert temperature to Kelvin , and then we can just substitute in the values.

To convert Celsius to Kelvin, you add 273.15 to the value

Looking at the balanced equation, ethylene gas is in a 1 : 2 molar ratio with

We can use the number of moles to calculate the volume of
