At 27.7mL sample CO2(g) was collected over water at 25.0 degrees celsius and 1.00 atm. What is the pressure in torr due to CO2(g)? (The vapor pressure of water at 25.0 degrees celsius is 23.8 torr.) What will the volume of CO2(g) be at the same temperature and pressure after removing the water vapor?
