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 $)$
