1. In a mixture of three gasses (A,B, and C), explain how are the partial pressures of the gasses related to the total pressure of the mixture? 2. Equal molar quantities of two gasses of molecular weight 4 and 40 are mixed. The pressure of the mixture is 1.2atm. What is the partial pressure of the lighter gas in this mixture? Explain. 3. When gasses are collected by water displacement, there is always water vapor (gaseous water) present. The amount of water vapor present depends on the temperature. The greater the temperature, the more water vapor present (this quantity is called the vapor pressure). A 1.00L volume of nitrogen gas measured at 290K and 0.978atm was collected at 290K by water displacement. Use Dalton's Law and the Ideal Gas Law to determine the number of moles of nitrogen gas that were collected. At 290K, the vapor pressure of water is 14.59 Torr. 1.
