Please Solve! And I wondering if they wanted us to use and previous information for part c). ? Because how I did it was just multiply the percent of O2 in the bubble (.6179) by 1167.3 after I converted to atm and got .949atm.
Thank you!

To whom it may concern, I need help with this question: Question: A scuba diver at 10 m below the surface of a lake, where the temperature is 5 degrees C, releases an air bubble with a volume of 16 cm^3. The bubble rises to the surface, where the temperature is 22 degrees C. What is the volume of the bubble (in cubic centimeters) just before it reaches the surface? (The density of water is 1000 kg/m^3 and air pressure...

Chame nsead tu age 06-17 Experiment 8: Molar Mass of a Volatile Liquid Purpose To determine the molar mass of a pure substance we need to find out (a) the number of moles in a given sample, and (b) the mass of the same sample. Molar mass is then: mass divided by moles Introduction Using the ideal gas equation, PV= nRT, we can determine the number of moles (n) of gas or vapor under measured conditions of pressure (P), volume...
