Need solution urgently   If 3.3 mL of 0.200 M Fe3+ solution is mixed with 2 mL of 0.00200M SCN- solution, and HNO3 is used to bring the final volume to 10 mL. What is the final concentration in M of the Fe3+  ion in the 10 mL test tube? Round and report your answer to the THIRD decimal place. Numeric only, do not enter the unit.

In the simulation, select the custom liquid from the dropdown list. The beaker will be filled to the 1.00 LL mark with the solution. Set the pHpH to 8.55 by entering the value in the text box provided above the pHpH scale in the panel called "pHpH." Once you adjust the pHpH, note the corresponding OH−OH− ion concentration in mol L−1mol L−1 as given in the graph on the right side of the simulation. Make sure to click the option "Concentration (mol L−1mol L−1)" under the “Water components” panel. Click on the Logarithmic scale below the graph.Find the pOHpOH of the solution.Express your answer numerically to two decimal places.

A stock solution of Na2B having a concentration of 0.1486 M is used to prepare four calibration standards, A-D in the table below, by diluting the indicated volume of this solution to a total volume of 50.00 mL. Complete the table by entering the molarity of B2- for each standard solution. Show an illustrative calculation for tube ‘A’. Use the dilution formula and express each result to one more digit than allowed by applying the rules of significant figures.

SHOW WORK. Calculate how many mL of 0.0857 M AgNO3 are required to prepare 100.00 mL of a 0.0133 M solution. Write out the problem on paper in order to answer the questions related to the setup and the calculation for this problem. Identify all of the terms in this problem and enter the numerical values (without units) in the appropriate blanks. Enter a question mark for the variable being calculated. Be sure to identify terms for the original solution as M, and V1, and terms for the final solution as M2 and V2. Do not leave any blank empty. M1 = V1= M2 = V2= Rearrange the dilution equation carefully needed to solve for the variable of interest. Identify which terms are in the numerator and which terms are in the denominator after rearranging. Do not leave any blank empty. Use the following abbreviations: original (or stock solution) molarity M1, volume of original solution = V1, final molarity of new solution = M2, final volume of new solution = V2 Terms in the numerator: Terms in the…
