My teacher has not explained how to find moles given pressure. I'm not sure how to start this problem. If anyone can help me at least get started, I would greatly appreciate it.
Question: At 25 degrees C, the vapor pressure of pure water is 23.76mmHg and that of a urea solution is 22.98mmHg. Calculate the molality of the solution.
I know that molality is (mols of solute)/(kg of solvent), but what relationship/formula will give me moles from this?
