Given the balanced equation representing a reaction:

Cao(s) + CO2(g) ---> CaCO3(s) + heat

What is the total mass of CaO(s) that reacts completely with 88 grams of CO2(g) to produce 200. grams of CaCO3(s)?

I don't understand what you have to do.

its 112g
because if you need a total of 200 and they already tell you that the co2 is 88, then subtract 88 from 200 to get 112
