a million% v/v of 1000 m3 of flue gasoline could be 10 m3. 10m3 is 10,000 dm3, that’s 10,000/24 = 416.sixty seven moles. you are able to, in accordance to your equation, consequently choose 416.sixty seven moles of calcium carbonate to react with it. Molar mass of calcium carbonate is a hundred g/mol, so which you will choose 416.sixty seven x a hundred = 40-one,666.sixty seven g or 40-one.sixty seven kg of calcium carbonate.
