Calculate the mass of `BaCO_(3)` produced when excess `CO_(2)` is bubbled through a solution containing `0.205` moles of `Ba(OH)_(2)`.

The solubility of CaCO_(3) is 7mg//L . Calculate the K_(sp) of BaCO_(3) when Na_(2)CO_(3) is added slowly a solution containing equimolar concentration of Ca^(2+) and Ba^(2+) and no precipitate is formed until 90% of Ba^(2+) has been precipitated as BaCO_(3) .
