Question

What will be the value of pb° if total pressure of the solution is given by p total =100 + 200xb atm?

Answer 1

We need to find Pb* which is the pure vapour pressure of b. Pure means that there are no other compound therefore Xb =1 . Putting 1 therefore Pb* = 100+200 = 300.

Mark as brainliest if it helped

Answer 2

bhai 300 hai sidha sidha
