How to calculate, thank you for the guidance. The saturation pressure of water vapor at 30 degrees Celsius is 4.2455KPa. Calculate the partial pressure ratio of water vapor = 4.2455KPa/0.25MPa ； The saturated vapor pressure of water at 15 degrees Celsius is 1.7056 KPa. Calculate the water vapor partial pressure ratio = 1.7056KPa/0.25MPa ； According to Doyle's law partial pressure ratio = molar ratio, we can get: at 35 degrees Celsius: The molar ratio of water to methyl chloride is N (water): N (methane chloride) = (4.2455/250): (1-4.2455/250) = 0.0173, that is, 1 mol of methyl chloride will contain 0.01726 mol of water. at 15 degrees Celsius: The molar ratio of water to methyl chloride is N (water): N (methyl chloride) = (1.7056/250): (1-1.7056/250) = 0.00687, that is, 1 mol of methyl chloride will contain 0.00687 mol of water. That is, the water content in 1 mol of methyl chloride is reduced by 0.01726-0.00687 = 0.01039 mol of water. I want to calculate the moisture precipitated after temperature changes. Is this algorithm correct?
