Auv-vis experiment was conducted at 592 nm for an aqueous solution of copper analyte in the presence of nickel interferent. the selectivity coefficient ka, i = 15.5. in one experiment, [cu2+] = 60.0 mm and [ni2+] = 15.0 mm. the average absorbance was measured as 0.465 au with an average blank signal of 0.0105 au. what is the absorbance, in au, due to cu2+ only?

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
