Any help is greatly appreciated!

Part 1: Find mixture and individual TLVs resulting from a liquid mixture comprising 40% methanol, 30% methyl acetate, and 30% methyl formate at a temperature of 298 K. Relevant data are given in Table 1. Vapor pressures can be calculated using Antoine's equation B In(psat) = A - C+T where psat is the vapor pressure in mmHg, T is the temperature in K, and A, B, and Care constants provided in Table 1. Part 2: A tank containing methanol has an opening with a diameter of 0.3 m. The tank and surroundings are at a temperature of 298 K. If the tank is within an enclosure where workers are present, determine the ventilation rate required (in m/min) to ensure that the TLV is not exceeded. TLV, ppm Table 1.
