A standard of barium nitrate for a gunshot residue analysis using atomic absorption spectroscopy is prepared by first dissolving 1.0035 g of the standard in distilled water containing 1 M nitric acid. The solution is brought to volume in a glass 500 mL volumetric flask with an uncertainty of 0.33 mL. This solution is diluted 1:10 by taking 10 mL (via an Eppendorf pipette, tolerance 0.97 L) and diluting this in 1% v/v nitric acid to a final volume of 100 mL in a volumetric flask with a tolerance of 0.1 mL. The balance has an uncertainty of 0.00005 g. (10 marks total) Show all steps

What is the final concentration of Ba2+? Hint: remember to report uncertainty
