Exposure to high concentrations of gaseous ammonia can cause lung damage. The acceptable short term ammonia exposure level set by the occupational safety and health administration is 35 ppm for 15 min. consider a vessel filled with gaseous ammonia at 30 mol/L and 10 cm diameter circular plastic plug with thickeness of 2 mm is used to contain the ammonia inside the vessel. the ventilation system is capable of keeping the room safe with fresh air, provded that the rate of ammonia being release is below .2 mg/s. if the diffusion coefficient of ammonia through the plug is 1.3*10^-10 m^2/s, determine whether or not the plug can safelt contain the ammonia inside the vessel.
