Any ideas...? |
here is an experiment we did in yr 12, not sure if it helps though but here is goes:
1. Find the mass of fuel burnt by weighting the fuel and the container befoe and after heating.
2. Find the number of fuel burnt
3. From the rise in water temp calculate the fuel produced by combustion of that many moles of fuel burnt using (delta)H=-m(delta)T
4. caluate how could've been produced by the combustion of 1 mole of fuel.
