Explain the total pressure of the atmosphere plus

Reference no: EM13264829

Consider the experiment shown below. The purpose is to determine the relative humidity of the ambient air (i.e., water vapor pressure divided by the saturated water vapor pressure at the specified temperature). The left side shows the apparatus initially, with a sample of ambient air trapped in the flask at a total pressure equal to the barometric pressure. The nearly filled buret whose tip is inserted through the plug in the mouth of the flask is then opened, and the water drains into the flask. The buret continues to drain, slowing gradually until coming to a complete stop, as depicted on the right side. At that moment, the total pressure of the gases inside the flask just equals the total pressure of the atmosphere plus the additional pressure of the water column remaining in the buret. Using the data shown on the diagram, calculate the relative humidity of the original ambient air sample. [76.1% relative humidity]
