# Calculating the number of volatile molecules in a container of known volume [closed]

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?

• Yes, this is a do-able calculation. – Chet Miller Sep 7 '20 at 23:50
