27) Deep-sea divers must use special gas mixtures in their tanks, rather than compressed air, to avoid serious problems. One such breathing mixture contains helium, oxygen, and carbon dioxide. Determine the partial pressure of oxygen when the total pressure in the tank is 201.4 kPa if PHe = 125.4 kPa and PCO2= 18.2 kPa? Must show all work that leads to answer for credit.
29) You have a sample of gas that occupies a volume of 42 mL at –89°C. What volume does the sample occupy at 77°C? Must show all work for credit.
30) A weather balloon containing 1975 L of gas at 25°C and 102.3 kPa rises to an altitude where the pressure is 21.5 kPa and the temperature is 12° C, calculate the volume of the balloon under these new conditions. You must show all work for credit.
31) Water has many unique properties because it is a polar molecule. Pick any one of water’s unique properties and explain (using a minimum of 2-3 sentences) both how and why this property would change if water molecules were nonpolar.
