The most abundant type of mammalian antibody circulating in the blood stream is IgG. A solution prepared from 0.798 g of a particular IgG in 250 mL of water shows an absorbance of 0.578 at 275 nm in a 1.00 cm cell. If the molar absorptivity of the IgG is 6.49 × 104 M–1 cm–1 at 275 nm, what is the molar mass of the IgG? Present your numerical answer in kg·mol-1 to 3 significant figures .
