Summer 2016 Name 2. A mixture of 0.220 moles CO, 0.350 moles H2 and 0.640 moles He, has a total pressure of 2.95 atm. What is the partial pressure of H2? (5 pts) 3. A sample of gas initially has a volume of 100 mL at 25 °C and 1.20 atm. What pressure will the sample have if the volume changes to 268 ml while the temperature is increased to 815 K? (6 pts) 4. A mass of 2.703 g of an unknown gas is introduced into an evacuated 5.00 L flask. If the pressure in the flask is 0.914 atm at 78 °C, which of the following gases might be in the flask? Show your work to get the credit. (6 pts) a) N2 b) C,H2 c) NH3 d) HCI e) NO Summer 2016 Name 2. A mixture of 0.220 moles CO, 0.350 moles H2 and 0.640 moles He, has a total pressure of 2.95 atm.
