If 0.500L of dry N2 was bubbles into an inverted flask through water to saturate it at 25.0C, what would be the total volume at the lab atmospheric pressure. Our pressure was : 757.5 mmHg

Answer 1

find the water vapor pressure from the temperature, and subtract that pressure from your observed pressure. At 25C, water vapor pressure is 23.8 mmHg (check that)

so your observed pressure then was 757.5mmHg-23.8mmHg.

Now, you have pressure and volume at that pressure, convert the volume to lab pressure.

V2=.5L*(755.5-23.8)/755.5
