Carbon tetrachloride (CCI4) is diffusing through benzene (CH), as the drawing illustrates. The concentration of CCI4 at the left end of the tube is maintained at 1.66 x 10'2 kg/ms, and the diffusion constant is 19.6 x 10'10 m2/s. The CC|4 enters the tube at a mass rate of 5.67 x 10'13 kg/s. Using these data and those shown in the drawing, nd (a) the mass of CCI4 per second that passes point A and (b) the concentration of CC|4 at point A. 5.00 . 10-3m Cross-sectional area = 3.00 . 10*1 m2 (a) Number n Units v (b) Number n Units v
