Nitrogen gas at high pressure and 298 K is contained in a 2-m × 2-m × 2-m cubical container made of natural rubber whose walls are 3 cm thick. The concentration of nitrogen in the rubber at the inner and outer surfaces are 0.067 kg/m3 and 0.009 kg/m3, respectively. The diffusion coefficient of nitrogen through rubber is 1.5 × 10?10 m2/s. The mass flow rate of nitrogen by diffusion through the cubical container is
(a) 8.1?×?10?10 kg/s (b) 3.2?×?10?10 kg/s (c) 3.8?×?10?9 kg/s (d) 7.0?×?10?9 kg/s (e) 1.60?×?10?8 kg/s
