At 25.8°C water has a vapor pressure of 24.912 torr. What is the mole fraction of water vapor at 25.8°C if {eq}P_{atm}{/eq} is exactly 1 atm? Dalton's Law of Partial Pressures: According to Dalton's law of partial pressures, ...
The water vapor transmission rate (WVTR) of a gas barrier coating is a critically important parameter for flexible organic device packaging, but its accurate measurement without mechanical stress to ultrathin films has been a significant challenge in instrumental analysis. At the current stage, no re...
