The concentration of Nat in the sea water sample was determined with atomic fluorescence spectroscopy (AFS). 35.00 mL of the sea water sample produce an AFS signal of 0.425. Then, 5.00 mL of 0.00215 M Nat standard were added to another 35.00 mL of the sea water sample, and this spiked sample gives an AFS signal of 0.724. What would be the concentration of Na+ in the sea water sample? 0.0268 M 0.00753 M 0.0109 M 0.587 M 0.00324 M
