Chemistry - Stoichiometry Question with Solution | TestHub

An unknown composition of a mixture of carbon disulphide and hydrogen sulphide was burnt in sufficient amount of oxygen. The resulting gases exert a pressure of 2.05 atm in a 16 L vessel at 400 K. The gaseous mixture required 300 ml of 2.0 M iodine solution to reach the end point, forming ${\mathrm{I}}^{-}$. Calculate the mole fraction of $\mathrm{C}{\mathrm{S}}_2$ in the original mixture.
