c) (6 pts) Calculate the molar mass of methane. 10. (10 pts) Terrence finds that all gases exhibit virtually the same behavior in response to temperature and pressure changes, no matter what the gaseous compound's formula mass or shape. The physical properties of gases depend on only four variables: pressure (P), volume (V), Kelvin temperature (T), and number of moles (n). All four variables can be changed simultaneously, but experimenting with only two at a time while keeping the other...
