Question: a,b,c,d
Kinetic Theory of Gas: Explanation of Pressure and Temprature Internal Energy of a gas, Ideal Gas Law 1. The average kinetic energy of a molecule, is called thermal energy, it is directly related to absolute temperature. KE (average per molecule) = 5m +(average) = 1 kg(kp = 1.38x10-23 /K) KT 2. The average speed of molecules in a gas: vrms=1 where vrms stands for root-mean-square (rms) speed. 3. The INTERNAL ENERGY of...

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...

Need help filling in my data sheet from a lab. My professor said
the pressure was 24.6 inches of Hg and that we needed to convert
that to moles. Im not sure i put that in the correct spot. I
included the lab protocol. Plz plz plz help me fill in the blanks
and let me know if i did something wrong Im very confused haha.
THANKS!!

Why do we measure the volume of the flask in this experiment with water rather than using the volume listed on the side? Select all correct answers that apply. Must include all correct answers for full credit. The volume is not accurate on a flask to the number of significant figures required for this experiment The volumetric markings on the flask do not extend to it's full height...
