help please!!!

Q2. [40 points, Manual Grading] A volatile chemical evaporates from an open container into a room of volume equal to your 44768 in ft3. The evaporation rate is determined to be 2500mg/min. The temperature is 77F and the pressure is 1atm. Assume a volatile species molecular weight of 100. a. If the air in the room is assumed to be well mixed, how many ft3/min of fresh air must be supplied to ensure that the concentration of the volatile is maintained below its TLV of 100ppm ? [20 pts] b. Estimate the maximum concentration of the volatile in the room in mg/m3, if the ventilation rate is maintained at values obtained from part a. [20 pts]
