At 318 K and 1.04 x 10-2 atm, the density of a gas is 1.75 x 10-5 g/cm3. (a) Find vrms for the gas molecules. (b) Find the molar mass of the gas.
vrms= sqrt (3RT/M)
The Attempt at a Solution
the main problem i am having here is units, and i am getting really frustrated, because i am a chem major, and this is chemistry!
in order to solve for the root mean square speed, i said, based on the above relationships, RT/M = p/d
so i plugged into vrms= sqrt (3p/d) BUT i don't know what units the density and pressure should be in to yield m/s for the final speed- i have no idea to even apply unit analysis here
