Given the Van der Waals constants for hydrogen chloride, below, calculate the pressure in atmospheres of 2.16 kilograms of hydrogen chloride gas in a $25.0\mathrm{L}$ container at $18^{?}\mathrm{C}$. $\begin{array}{l}a(HCl)=3.65L^2\mathrm{atm}/{\mathrm{mol}}^2\\ b(HCl)=0.0406\mathrm{L}/\mathrm{mol}\end{array}$ (Note - depending on how BrightSpace generates the data it gives you, the sig figs may not be correct in the answer. sorry. Your mass and the overall sig figs should be three. Make sure you enter your final answer to three sig figs or you won't get credit for it.)
