An HPLC analysis is carried out on codeine phosphate linctus. The linctus is diluted to 50.00 mL with water prior to analysis. The weight of the linctus analyzed was 13.5000 g. The density of the linctus was 1.2522 g/mL using a densitometer. Area of the 0.076050% w/v codeine phosphate standard was 85,585. The area of the codeine phosphate peak obtained from the linctus was 62,880. Calculate the percent w/v of codeine phosphate in the linctus. Please show all work.

Consider the laboratory on HPLC analysis of components in diet soft drinks. Your standard solutions for caffeine were prepared from a stock solution of 0.40 mg/mL caffeine, from which you drew, 1.0, 2.0, 3.0, 4.0 and 5.0 mL and diluted each one to 50.0 mL. Calculate the concentration of the most concentrated standard solution. For the same lab as in problem 1, suppose you plotted peak height (y-axis) vs. concentration in mg/mL (x-axis), and the slope was found to be...

When a neutralization reaction was carried out using 100.0 mL of 0.7890 M NH3 and 100.0 mL of 0.7940 M acetic acid, ∆T was found to be 4.76oC. The specific heat of the reaction mixture was 4.104 J g-1 K-1 and its density was 1.03 g/mL. The calorimeter constant was 3.36 J K-1. Show all work below for the following calculations: a.) heat absorbed by the reaction mixture b.) heat absorbed by the calorimeter c.) total heat absorbed d.) number...

7. 25 ml of 6 M NaOH was diluted with water to 400 ml. What is the pH and pOH of the final solution? What is the [H+] and [OH-]? (Remain calm; remember the formula for dilution from the previous lab session: (V1)(C1) = (V2)(C2) ) 8. A solution was made by dissolving 10 g of NaOH (formula weight 40 g/mole) in water and the final volume brought to 500 ml. What is the pH, pOH, [H+] and [OH–] of...

Assuming you weighed out a 2.3684 g sample of your unknown, and dissolved and diluted it as in the procedure below, and it took 35.63 mL of a 0.1025 M HCl titrant to reach the endpoint, what are the weight percents of Na2CO3 and NaHCO3 in your unknown sample? Hints: -Set g Na2CO3 = X -Eqn A: bicarbonate + carbonate = diluted weighted mass (remember, the mass is not 2.3684, you diluted it before you titrated it.Calculate the diluted g...

Add to the solution the required amount of concentrated ammonia. Transfer this quantitatively to a 100 mL volumetric flask, dilute to volume, and mix thoroughly. 10.00 mL of this is pipetted into a 100 mL volumetric flask, the required amount of concentrated ammonia is added and diluted to volume. This is Standard 1. Standard 2...

Below is the background info for the lab assignment. The 4 blank boxes are the questions I would like answers too. The end point for the fine titration was 35.90 mL in the burette when the solution turned bright green again. And the coarse titration I got 35.36mL as the end point. 35.9 mL is exact in case you need that info. Thanks! Background In this lab, we will determine the amount of alcohol (ethanol), C2H5OH, in a commercial vodka...
