    Thermo cycles with only T and mol

    Homework Statement A three-step cycle is undergone by 3.8 mol of an ideal diatomic gas: (1) the temperature of the gas is increased from 210 K to 550 K at constant volume; (2) the gas is then isothermally expanded to its original pressure; (3) the gas is then contracted at constant...

    Find V rms and MM using density

    Sorry about that, units that I got: a) m/s b) kg Also for b that was a typo, I meant to put in 4.04x10-8.

    Find V rms and MM using density

    Homework Statement At 332 K and 1.28 x 10-2 atm, the density of a gas is 1.89 x 10-5 g/cm3. (a) Find vrms for the gas molecules. (b) Find the molar mass of the gas.Homework Equations Vrms=√(3RT/M) (RMS speed) PV=nRT (Ideal Gas Law) D=m/V (Density) M = m/n (Molar mass = mass/number of moles)...
