A student carried out the following experiment to measure the pressure of carbon dioxide in the space above the carbonated soft drink in a bottle. First, she weighed the bottle (853.5 g). Next, she carefully removed the cap to let the CO2 gas escape. She then reweighed the bottle with the cap (851.3 g). Finally, she measured the volume of the soft drink (452.4 mL). Given that the Henry’s law constant for CO2 in water at 25°C is 3.4 × 10−2 mol/L • atm, calculate the pressure of CO2 over the soft drink in the bottle before it was opened. Explain why this pressure is only an estimate of the true value.
