Carbon tetrachloride (CCl4) is diffusing through benzene (C6H6), as the drawing illustrates. The concentration of CCl4 at the left end of the tube is maintained at 1.09 x 10-2 kg/m3, and the diffusion constant is 16.7 x 10-10 m2/s. The CCl4 enters the tube at a mass rate of 5.22 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 CCl4 at point A.
