7. A gas takes up a volume of 15 liters, has a pressure of 3.3 atm, and a temperature of 299 K. If I raise the
temperature to 350 K and lower the pressure to 1050 mmHg, what is the new volume of the gas?
8. I have an unknown volume of gas held at a temperature of 115 K in a container with a pressure of 60.0
atm. If by increasing the temperature to 225 K and decreasing the pressure to 30.0 atm causes the volume
of the gas to be 25 liters, how many liters of gas did I start with?
9. A gas has a temperature of 14oC, and a volume of 5.5 liters. If the temperature is raised to 29oC and the
pressure is not changed, what is the new volume of the gas?
10. A gas that has a volume of 28 liters, a temperature of 65oC, and an unknown pressure has its volume
increased to 36 liters and its temperature decreased to 35oC. If I measure the pressure after the change to
be 2.0 atm, what was the original pressure of the gas?

Calculate the ratio of h+ ions to oh– ions at a ph = 7. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1
