Step 1: Understand the mole fraction The mole fraction of methanol (CH₃OH) is given as 0.25. This means that in a solution, there are 0.25 moles of methanol for every 1 mole of solution. Step 2: Calculate moles of water Since the total mole fraction must equal 1, we can find the...
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, ...
