I Was doing a quick mole calculation for this reaction:
MgCO3 + H2SO4 ---> MgSO4 + CO2 + H2O
I found that there were 0.005 moles of sulphuric acid and 0.00356 moles of magnesium carbonate (using the information I was provided with).
I was wondering which number of moles I'd use to apply stoichiometry to the equation above, since as the sulphuric acid is in excess. Would I minus the lowest ratio of moles from the highest? I'm not entirely sure!

What exactly are you trying to work out? If it is yield then just use the moles of magnesium carbonate. You don't need to take the difference or anything.

I need to work out the volume of CO2 evolved (which according to the mark scheme is 71.4 cm3).
