Sorry if this is in the wrong forum, and I've never done this before, but I'm at work and I'm bored, so I'd really appreciate any help. 2 Questions: 1. How do I find the pressure of water at different temperatures? I'm trying to find the pressure at 98 degrees celcius. 2. Here's the actual question: The vapor pressure of a mixture of 1.5 mol each of A, B, and C at 50 degrees Celcius is 100, 200, and 300 mmHg respectively. WHat pressure must be exerted on the surface of a solution for boiling to begin at 50 degrees celcius? Thanks in advance...sorry if this clogs the forum.
