Cytochromes are proteins which contain iron (usually only one), and are important in biological electron transport. If a 2.3 mg sample of a newly discovered cytochrome from the bacterium Azotobacter vinlandii contained 10.3 micrograms of iron, what is the molecular weight of this new protein? You can assume it contains only one mole of iron per mole protein
