Calculation of methanol vapor concentration
Thread Content
Chemical engineering principle question: At a pressure of 101325 Pa and a temperature of 25°C, methanol reaches saturation in air. Find: ① The saturated vapor pressure Ps of methanol ； ②The composition of methanol in the air (expressed as volume concentration cA and mass concentration ρA) is known; the methanol antoine constants are A=7.87863, B=1473.11, and C=230. Could someone please tell me how to calculate these values? Need the process! Also: What is the difference between vapor saturation in air and conceptual saturation?
It’s quite complicated; I’m not sure if PV=NRT can be used to calculate it.
No one is paying attention; please help out by pushing it yourself
