# What energy is associated with the complete combustion of a 20*g mass of ethane?

Jul 22, 2017

Well the reaction we consider is.....

${C}_{2} {H}_{6} \left(g\right) + \frac{7}{2} {O}_{2} \left(g\right) \rightarrow 2 C {O}_{2} \left(g\right) + 3 {H}_{2} O \left(l\right) + \Delta$

#### Explanation:

And this is the subject of MEASUREMENT, not calculation. So you should have quoted some thermodynamic parameters in the question.

Clearly, we can calculate a molar quantity of ethane, =(20*g)/(30.07*g*mol^-1)=??*mol......
