the fugacities of pure components $(1)$ and $(2)$ at $25$ C temperature are given as $646$ mmHg and $283$ mmHg respectively.The partial fugacities of components $(1)$ and $(2)$ were measured as $332$mmHg and $190$ mmHg in a mixture of them at the same temperature. Ithe mole fraction of component $(2)$ in the mixture is $0,6$ A$-$Calculate the activity coefficients, and the excess chemical potentials of components $(1)$ and $(2)$ B$-$ The excess Gibbs free energy of $1$ mol mixture at the same temperature $($ PLASE DONT USE CHATGBT$)$
