Is it possible to calculate the number of volatile molecules (so only those in the gaseous phase) in a container of known volume, if the vapor pressure of the compound is known? So for example, if you have a container with a volume of $10\ \mathrm{ml}$ containing $3\ \mathrm{ml}$ of a Compound X with a vapor pressure of $10\ \mathrm{mmHg}$ at $\pu{25 ^\circ C}$, what is the number of gaseous molecules of X in the container?

1$\begingroup$ We have a policy which states that you should show your thoughts, effort and attempts to understand underlying principles and solve the question. It'll make us certain that we aren't doing your homework for you. ( As homework is considered literal homework, self-study questions, puzzles, worked examples etc.) Next time, provide your full reasoning or thoughts on this, otherwise, the question may get closed. See Homework. This question may get closed anyway. $\endgroup$– PoutnikCommented Sep 8, 2020 at 3:15
