Is anyone doing the AS Chemistry Planning Exercise for OCR syllabus?

Hi could someone please tell me how you work out the concentration of sulphuric acid after calculating the no. of moles of carbon dioxide produced, in the gas syringe experiment. I know its something to do with using a mole to mole ratio but i am not sure how to do this. Plus i have to do hand this in tomorrow!! any help much appreciated. thanks. :frown:

hihihihi

i'd guess that it be something to do with working out moles of CO2 produed by moles= volume/24dm^3
then using the molar ratio of CO2 to sulphuric acid to calculate moles of sulpuric acid and then applying concentration = moles/volume to calculate conc. of acid (because u wil have uced a certain amount of acid which u know)

something like that??
