A sample of CO2(g) produced in a reaction is collected in a 125 mL container at 28 °C and 0.98 atm. The gas is then bubbled through 250 mL of 0.150 M Ba(OH)2(aq), where it reacts according to
Ba(OH)2(aq) + CO2(g) → BaCO3(s) + H2O(l)
Assuming all the CO2 reacts and the volume of the solution does not change appreciably, what mass of BaCO3(s) precipitates?
a) 0.85 g
b) 0.98 g
c) 1.10 g
d) 0.76 g
