일반물리학 1 — The Kinetic Theory of Gases: Problem 44

44 At 546 K and \( 2.00 \times 10^{-2} \text{ atm} \), the density of a gas is \( 1.24 \times 10^{-5} \text{ g/cm}^3 \). (a) Find \( v_{\text{rms}} \) for the gas molecules. (b) Find the molar mass of the gas and (c) identify the gas. See Table 19-1.
