(a) A vessel contains a binary mixture of $\mathrm{O}_{2}$ and $\mathrm{N}_{2}$ with partial pressures in the ratio 0.21 and 0.79 at $15^{\circ} \mathrm{C}$. The total pressure of the mixture is 1.1 bar. Calculate the following (i) Molar concentrations (ii) Mass densities (iii) Mass fractions (iv) Molar fractions of each species.
Explanation
To calculate the molar concentrations, mass densities, mass fractions, and molar fractions of each species in the binary mixture, we use the ideal gas law and the definitions of mass density and molar fraction.
