A sample of barium hydroxide, Ba(OH)2, is known to have become contaminated with barium
carbonate, BaCO3, by reaction with CO2 in the air. A 2.00 g sample is titrated with 0.450M HCI
and it is found that 55.56 mL of HCl are required for neutralization. Calculate the percentage by
mass of BaCO3 in the sample.
