An open container was monitored and found to have a toluene evaporation rate of \(0.1 \mathrm{~g} / \mathrm{min}\). The ventilation rate is \(2.84 \mathrm{~m}^{3} / \mathrm{min}\), the temperature is \(27^{\circ} \mathrm{C}\), and the pressure is \(1 \mathrm{~atm}\). Estimate the concentration of toluene vapor in the enclosure and compare it to the TLV of \(50 \mathrm{ppm}\). Perform the calculation for a \(k\) of 1.0 and 0.1 .
