Beer's Law Calculations: A. Dilution Calculations 1. Use the actual mass of cobalt(II) nitrate hexahydrate you used to calculate the concentration of your stock solution. 2. Calculate the concentration of your diluted solutions. The easiest way to do this is with the equation MiV2-M2V2. Show the work for the calculation of the concentration of at least one of your dilute solutions. 3. Make a table...

solve all 3 dont waste my answer
1. Check Beer's Law by plotting absorbance vs molar concentration using 2. Is Beer's Law valid for this system? Explain your answer. 3. If Beer's Law is valid, the value of "E" should be constant. Use A-ECPL or E = A/(EL) and the data from Table II to calculate values of E for the five solutions below. The value of L is normally 1 cm so E - A/C in this experiment. Table...

ii) Nickel analysis - Prepare three standard nickel solutions using the following procedure. Accurately weigh approximately 1.0 g of [Ni(H20)6]504 into a 50 mL volumetric flask. Add 10 mL of D.I. water followed by 10 mL of 1 M H2SO4(aq) to dissolve the salt and then dilute to the mark with deionized water. Pipet 10 mL of the solution into one 25...
Suppose 15.2 g of nickel(II) iodide is dissolved in 200. mL of a 0.50 M aqueous solution of potassium carbonate.
Suppose 15.2 g of nickel(II) iodide is dissolved in 200. mL of a 0.50 M aqueous solution of potassium carbonate. Calculate the final molarity of nickel(II) cation in the solution. You can assume the volume of the solution doesn't change when the nickel(II) iodide is dissolved in it. Be sure your answer has the correct number of significant digits.
