1.to find atmospheric pressure, go to your local weather and find the pressure in inches. convert to mmhg by multiplying by 25.4. record answer in data table. (patmosphere=25.4 x local weather pressure reading) 2.since the gas in your graduated cylinder is a mixture of butane and water vapor, you must determine the partial pressure of the butane, pbutane, alone. to do this, use the chart listed below and record the partial pressure of the water vapor, pwater, at the temperature you recorded. use the following formula to compute the partial pressure of the butane. (pbutane =patmosphere - pwater) pbutane =
