A 16.48 g sample of potassium permanganate is dissolved in a 250.0 mL volumetric flask. A 125.1 mL sample of the potassium permanganate solution is added to 75.3 mL of 5.110 M hydrobromic acid in which 32.3 mL of ethanol has been dissolved (d = 0.7891 g/mL) in 3.337 L sealed reaction vessel at 22.1ºC and 743 mmHg. What is the pressure of carbon dioxide gas?
