1. A sample of gas has 36 trillion molecules, and the average kinetic energy
of each molecule (at 27°C) is 6.22x10-14 ergs.
What is the thermal energy (in ergs) of the sample of gas? Explain your
reasoning and show your calculations.

What is the independent variable in this investigation? mass volume sample number substance density

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.
