Problem $1\mathrm{.}8$

The van der Waals equation can be applied to describe the relationship between real gases over a range of temperature and pressure values.

$(P+\frac{n^{2}a}{V^2})(V-nb)=nRT$

where $P$ is the pressure $(217\mathrm{.}12$ atm$)$

$n$ is the number of moles $)$

$V$ is the volume $(1$ Liter$)$

$a$ is a gas$-$specific constant $-$atm$/$mol $($:${?}^2$
