Assignment Help Physics
##### Reference no: EM13543084

The diffusion constant for the alcohol ethanol in water is 1.24 10-9 m2/s. A cylinder has a cross-sectional area of 3.85 cm2 and a length of 1.86 cm. A difference in ethanol concentration of 1.66 kg/m3 is maintained between the ends of the cylinder. In one hour, what mass of ethanol diffuses through the cylinder?
