At 25°C, the emf (in volts, rounded off to three decimal places) of the cell, $\mathrm{Ag}|\mathrm{AgBr}(\mathrm{s})| \mathrm{Br}^{-}(\mathrm{a}=0.20), \mathrm{Cu}^{2+}(\mathrm{a}=0.48), \mathrm{Cu}^{+}(\mathrm{a}=0.24) \mid \mathrm{Pt}$ is ____ (Given: The standard emf of the cell is $0.082 \mathrm{V} ; \mathrm{R}=8.314 \mathrm{JK}^{-1} \mathrm{mol}^{-1} ; \mathrm{F}=96500 \mathrm{C} \mathrm{mol}^{-1}$ )
