Question: The molar absorptivity for the complex formed between bismuth (III) and thiourea is 9.32 ( 103 L cm21 mol-1 at 470 nm. Calculate the range

The molar absorptivity for the complex formed between bismuth (III) and thiourea is 9.32 ( 103 L cm21 mol-1 at 470 nm. Calculate the range of permissible concentrations for the complex if the absorbance is to be no less than 0.10 nor greater than 0.90 when the measurements are made in 1.00-cm cells.
