A 0.I M solution of compound A shows 50% transmittance when a cell ofI cm width is used at, nm. Another 0.1 M solut ion of compound B gives the optical density value of0.176l usingI cm cell at 1 nm What will be the transmittance ofa solution that is simultaneously 0.1 M in A and 0.1 M in B using the same cell and at the same wave length ? log 20 1.301; log 30 1.4771; log 50 =1.699] (a) 33.3% (b) 50% (C) 66.7%% (d) 70%
