In the HQS-Mg fluorescence part of Lab 6, a calibration curve is made of fluorescence intensity vs. MgCl₂ concentration (M). The standard solutions for the calibration curve were made by mixing a small amount of 0.01 M MgCl₂ with some HQS solution. Calculate the concentration of MgCl₂ (M) in each of the following standards. Report your concentrations to 3 sig figs.

Transcribed Image Text:In the HQS-Mg fluorescence part of Lab 6, a calibration curve is made of fluorescence intensity vs.
MgCl2 concentration (M). The standard solutions for the calibration curve were made by mixing a
small amount of 0.01 M MgCl2 with some HQS solution. Calculate the concentration of MgCl2 (M)
in each of the following standards. Report your concentrations to 3 sig figs.
