Have you taken into consideration the molar ratio e.g if 2 moles are produced etc?

yup, that's why i tried writing them out, CO2 doesn't have any coefficient in front of any of them, and the HCl:CO2 ratio is the same for (a) and (c). do i have to apply the molar ratio elsewhere?

Ohh I just realised, each is 1 g so convert that into moles for each and some will have more moles than other meaning more co2
