The following question is based on UV Spectroscopy quantitative analysis

please find the concentration of the unkown using the simultaneously equation method show all work

Given the following information

simultaneous equation:

dilution standards absorbance at different concentration.

unkown has an absorbance of 0.57 at 577nm and 0.82 at 511nm

unknown composes of both chromium (lll) nitrate and Cobalt (ll) nitrate at an unknown concentration. Given the know concentration and the absorbances of standards of chromium (lll) nitrate and Cobalt (ll) nitrate at their respective lambda max, find the concentration of each substance in the unknown. chromium (lll) nitrate lambda max is at 577nm and Cobalt (ll) nitrate lambda max is at 511nm.

A1=acr1bccr+acolbccoA2=acr2bccr+aco2bcco Cobalt (II) Nitrate (Lambda max 577nm ) Cobalt (II) Nitrate (Lambda max 511nm ) Chromium (III) Nitrate (Lambda max 511nm ) Chromium (III) Nitrate (Lambda max 577 nm) Chromium (III) Nitrate (Lambda max 511nm )
