Acontainer holds 1.7 mol of gas. The total average kinetic energy of the gas molecules in the container is equal to the kinetic energy of a 7.0x10'3 kg bullet with a speed of 670 m/s. What is the Kelvin temperature of the gas? Number n Units v Carbon tetrachloride (CC14) is diffusing through benzene (C6H6), as the drawing illustrates. The concentration of CC14 at the left end of the tube is maintained at 1.94 x 10-2 kg/m3, and the diffusion constant is 15.0 x 10-10 m2/s. The CCl4 enters the tube at a mass rate of 5.33 x 10-13 kg/s. Using these data and those shown in the drawing, find (a) the mass of CCl4 per second that passes point A and (b) the concentration of CC14 at point A. 5.00 x 10 m Cross-sectional area = 3.00 x 10 4 m2 A -CCla (a) Number Units (b) Number Units
