What volume of O2 (m3) is needed for the complete combustion of 131 g C2H6
« on: November 15, 2006, 10:21:38 PM »
Anyone know how to do this problem?

What volume of   O2 (m3)   is needed for the complete combustion of   131 g   of   C2H6   at   20.0oC   and   100.0 kPa?

The balanced equation is:

2C2H6 + 7O2 --> 4CO2 + 6H2O
&
V= nRT/P

I thought (15.4)(.08206)(293.15) / (.987167) was correct but when I submit it on my online quiz it says incorrect...

Anything is appreciated!!

Did you enter the answer in litres or metres cubed?

Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex
