what you get for energy q and the ratio q with relative atomic mass for sulpuric acid when ammonia weighs 68 g

thats the question i struggled on.. what did you get?

yeah I failed it.

ratio q i got 192 g because 34 g doubled to 68 g, so you doulbe 96 g
energy i did 4.2 [s.hc] X 27 [temp change] X 1.5g [mass]
= 170.1 g

I got the same mark as you in the mock and found this paper alright. I had a mind blank on the rock questions though.
