4. If you digested 25 mg of pure ferrocene in nitric acid and then diluted the resulting solution up to 500 mL with 1% aqueous hydrochloric acid, what would be the concentration of iron in solution (provide an answer in both mg/L and mol/L)?
A 11.17 mg ore sample containing copper is digested with acid, filtered and transferred to a volumetric flask and diluted to exactly 200.00 mL. A 10.00 mL aliquot is transferred to a 100.00 mL volumetric flask containing zincon reagent and a quantity of a pH 9 buffer solution. It is then diluted to the mark and mixed thoroughly. The measured absorbance of the resulting blue solution at 600 nm was 0.326 which corresponded to a Cu(II) concentration of 0.498 ppm...
A 0.5g sample was digested with 10ml of Nitric acid solution Then diluted to 1:10, 1:3 ration What is the amount of Mg, Zn, in ppm if given the following: Show all calculation work please step by step Mg (mg) Zn(mg) Fe (mg) Sample weight (g) 0.05 0.0014 0.0017 0.5
A chemist dissolves 306. mg of pure nitric acid in enough water to make up 140. mL of solution. Calculate the pH of the solution. Round your answer to 3 significant decimal places. 0-10
A chemist dissolves 333.mg of pure nitric acid in enough water to make up 100.mL of solution. Calculate the pH of the solution. Be sure your answer has the correct number of significant digits.
A chemist dissolves 540. mg of pure nitric acid in enough water to make up 90.mL of solution. Calculate the pH of the solution.Round your answer to 2 significant decimal places.
A standard iron solution was prepared by dissolving 0.0100 g of pure iron in acid then transferring to a 50.00 mL volumetric flask with orthophenanthroline as a complexing agent. At a wavelength of 540 nm, the absorbance of the standard was 0.239 in a 1.00 cm cuvette. A 0.149 g sample of an iron ore was crushed and digested in 5 mL of concentrated acid. The digested sample was then transferred to a 10.00 mL volumetric flask and diluted to...

Part A If 10.0 mL of glacial acetic acid (pure HC2H3O2) is diluted to 1.70 L with water, what is the pH of the resulting solution? The density of glacial acetic acid is 1.05 g/mL. Express your answer to two decimal places.
If 15.0 mL of glacial acetic acid (pure HC2H3O2) is diluted to 1.70 L with water, what is the pH of the resulting solution? The density of glacial acetic acid is 1.05 g/mL pH=?
