Chemistry - Liquid Solution Question with Solution | TestHub

Here it is given that
$\text{π}=2.5\text{atm,}\text{T}=24+273=297\text{K},\text{S}=0.0821\text{lit}.\text{ atm}{\text{K}}^{-1}\text{mo}{1}^{-1}\text{C}\text{=}\text{?}$
We know that$\mathrm{\pi }=$CST or$\mathrm{C}=\frac{\mathrm{\pi }}{\text{ST}}=\frac{2.5}{0.0821\times 297}=0.1025$moles/litre
