Howmany gram of `CO_2` would be required to be passed through a tank of lime water to proudce 100 grams of `CaCO_3`? (Ca= 40,C = 12,0= 16).

How many gram of CaCO_3 will react with exces of dilute HCl to produce 66 gm of CO_2 ? (Ca = 40, C = 12, O = 16)

What happens when excess of CO_2 gas is passed through clear lime water?

If CO_2 gas is passed through 500 ml of 0.5(M) Ca(OH)_2 the amount of CaCO_3 , produced is
