Osmotic Pressure vs Vapor Pressure

[Michael Noto]

If I were asked to calculate the vapor pressure, and I calculated the osmotic pressure and converted it to mmHg, Would I get the right answer?

I believe so, but l

Not like these things are completely unrelated, but in general no, these are separate phenomena.

Can you elaborate on why you think what you did is correct?

Basically I was given some data about a solution and was asked to find the Vapor Pressure in mmHG. After calculating the Molarity, I had all of the pieces to solve for PI=iMRT so I did that then converted the answer in ATM to mmHG.

That's what you did, not why you think it is correct.

Calculating something just because you have data to do so, when you are asked to calculate something else, is rarely a correct approach to solving problems.

Maybe you want to look up Henry's and Raoult's laws.
