How to solve this ?

Question # 1: Sixty gallon drum are being filled with 2-butanol (C4H9OH). The drums are being splash-filled at the rate of 25 drums per hour. The bung opening through which the drums are being filled has an area of 8 cm2 . Estimate the ambient vapor concentration if the ventilation rate is 2000 ft3 /min. The vapor pressure of 2-butanol is 0.6 mmHg under present operating condition. (Molecular weight of C=12, O=16, H=1). k mixing factor = 0.6, 1 drum = 55 gallons.

Question # 2: A tank truck carrying benzene (C6H6) has overturned on the highway and a pool of benzene 50 m in diameter has formed. It is 1-pm in the afternoon on a clear, sunny day, the ambient temperature is 30C. (P Sat Benzene= 0.156 atm). Estimate the evaporation rate of benzene in kg/s.
