The reaction between an unknown volume of CO 2 with a solution of Ba (OH) 2 produced 6.35 g of BaCO 3. Answer: what is the volume (in CNTP) of CO 2 that reacted?

CO 2 (g) + Ba (OH) 2 (aq)  BaCO 3 (s) + H 2 O (l)

Calculate the mol of BaCO₃ , how much CO₂ it correspond. Convert this to the volume . By using molar volume or the ideal gas equation.
