Do the following calculations and record the results on your Data Sheet. The numbers in parentheses refer to the numbered liner on the Data Sheet. 1. Find the volume of wet air. The volume of wet air is the same as the sum of the volume of the flask and the added volume of syringe. This volume is recorded on your Data Sheet (2). 2. Convert the Kelvin temperature (K) to an equivalent temperature in Celsius (°C), using Bauation 1. K- °C+ 273.2 (Eq. 1) Record this temperature on your Data Sheet (4). 3. Find the water vapor pressure at this temperature in the Table 1. If you cannot find the temperature which you look for in the table, use the water vaper pressure at the nearest temperature. Record this water vapor pressure on your Data Sheet (5). 4. Covert the water vapor pressure (mm Hg) to an equivalent pressure in atm, using Equation 2. 1 atm = 760 mm Hg (Eq. 2) Record this water vapor pressure on your Data Sheet (6). 5. Find the pressure of the dry air. Subtract the water vapor pressure (6) from the barometric pressure (3). Record this pressure on your Data Sheet (7). 6. Find the volume of dry air. Multiply the volume of the wet air (2) by the pressure of the dry air (7), divided by the barometric pressure (3), using Equation 3. (Pressure of dry air, atm) (barometric pressure, atm) volume of dry air, ml = (volume of wet air, mL) (Eq 3) Record this volume on your Data Sheet (8) 7. Find the volume-to-termperature ratio (V/T), using Equation 4., Divide the volume of dry air (8) by the Kelvin temperature (1). (volume of dry air, mL) (temperature, K) mLK-= %3D 8.
