### Different Concentrations

Is there ever going to be a time where they ask us to find the K for concentration if the problem is given in terms of gas? If so, how would we go about this?

You can convert between partial pressure and molar concentrations using the Ideal Gas Law:
$PV=nRT$
$P=\left ( \frac{n}{V} \right )RT$
$P=\left ( concentration \right )RT$
$concentration=\frac{P}{RT}$
