The mole fraction of ethyl alcohol in it...

The mole fraction of ethyl alcohol in its solution with methyl alcohol is `0.80.` The vapour pressure of ethyl alcohol in the solution is 40mm of Hg. What is its vapour pressure in solution if the solution is ideal ?

Text Solution

Verified by Experts

The correct Answer is:
32 nn
`p_(C_(2)H_(5)OH)=x_(C_(2)H_(5)OH)xxp_(C_(2)H_(5)OH)^(@)=0.80xx40mm=32mm.`
