I guess that would depend on the volumes of each solution that you had.How much product would you get if you had 10 ml of solution A? 10 ml of solution B? 10 litres of solution A? Of B?
In some cases, yes you would get more gas from the 1.0M solution than the 0.5M, but not others, do you appreciate why?
Do you know what a limiting reagent is?

Which is the limiting reagent if you had 10 ml of each solution? What about 10 litres?
QuoteWhich is the limiting reagent if you had 10 ml of each solution? What about 10 litres?OK, this is what I would presume - I have not actually conducted the expt.
10ml0.5 moll: Acid1 mol: CaCO310 lCaCO3 in both casesSo, if we presumed we were using a 10l solution, where the mass of CaCO3 was constant, would 1 mol give off more gas?Thanks
What's the balanced equation for the reaction you are (hypothetically) carrying out?
as you suggest, in the 10 litre case the CaCO3 is the limiting reagent then the amount of gas would be limited by that, and so in both the 1M and 0.5M case you should give off the same amount of product.
