I got about 2643789kj and 55200L required for the hydrogen one. Im pretty sure its right, but i could be mistaken.jaggy snake said:I thought it was a fair paper, quite easy and didn't really ask about any of my weaknesses (except buffers).
Lots of calculations too
oh btw, what were the answers for the HCl concentration and the volume of hydrogen needed for the same amount of energy as 80L of petrol or whatever it was?
Same as you for the first 2 can't remember what i got for the titration but i remember getting something along those lines.fishbulb said:I got about 2643789kj and 55200L required for the hydrogen one. Im pretty sure its right, but i could be mistaken.
I got 0.098mol/L for the titration one as well.

Did you guys do the 1:2 mole ratio of Na2CO3:HCl thing?
And then find the concentration of HCl, using the titre volume (23.45mL)
ah fuck lolJamesTockuss said:I think the titre volume (23.45mL) was for the Na2CO3 ---- while the 25mL was for the HCl samples.
