Potassium standards gave the following emission intensities at 404.3 nm. emission from the unknown was 417. find the [k+] and its uncertainty in the unknown. (use a spreadsheet / graphing program to make a concentration vs. emission signal plot, then find the [k+] and its uncertainty in the unknown.)
