If I used 50 ml 0.15M hyrocholoric acid (case I) to react with marble chips instead of 100mL 0.1M hydrocholoric acid,(case II)  then I know that the rate of reaction for case II would be much faster than (I). But comparing the volume of carbon dioxide evolved, case (i)produces far more carbon dioxide gas than case (ii), what is the reason for that?

amount of product formed depends on amount of reactant consumed

But isn't the number of moles of hydrocholoric acid in case (ii) is greater than in (i), thus the amount of products formed will be more?

[Donaldson Tan]

the amount of carbon dioxide formed depends on the amount of the limiting reagent.
