You are to prepare capsules that contain 0.125 g of a drug. You have four partial containers of medicatiog, which weigh 3.2 g, 1.784 g, 2.46 g, and 5.87 g. Assume you have weighed each of the four containers with the same scale, and the accuracy is known to the hundredth gram. a Which amount will need to be rounded? b. Which amount is not as accurate as it should be? c. What is the amount of the medication that will be left over after making as many 0.125 g capsules as possible?

Why does one see methyl orange as orange in color? What blank would be used to standardize this spectrophotometer?

Describe the preparation of the following solutions include all mathematic calculations and equipment of the laboratory needed A.500 mm of a solution of KNO 1.50 M B. 150 g of a solution 5.0% of NaC2H3O2 C. 500 mm of a solution of NaOH 0.50 M from a solution of NaOH 6.0 M

Explain the color changes observed throughout the peroxide value of oil experiment. Materials:1. Old and fresh oil samples2. Distilled water3. Acetic acid/chloroform solution4. Saturated potassium iodide solution5. Sodium thiosulphate (0.01M)6. 1% Starch indicator: dissolve 1g of starch in 10 ml of water and then add 90 ml of hotwater to it

A calibration curve for the absorbance of an unknown is shown below. What would be the concentration of a sample with absorbance of 0.45. Give the answer with the correct unit.

A patient is to receive Tazidine by intramuscular injection.  A 10.0-mL vial contains 1 gram of dry powder that was reconstituted with 3 mL of sterile water.  The reconstituted solution contains 340 milligrams Tazidine in 1.00 mL of volume.  How much solution should be injected if a patient needs to receive a 0.30 gram dose?  Enter the numerical part of the answer in the first box (using correct significant figures) and the correct unit in the second box.

Define Radionuclide Purity if: t_measurement = 300 s , N1 = 85362 counts, N2 =1278 Counts,I1 =11,7% , I2 =6,55%, ε2 =0,057 and ε1 =0,097

You are given a 27 % (w/v) solution of psicose.                                                Molar mass: psicose (C6H12O6) = 180.156 g/mol.    ou have a 0.75 mg/mL solution of bovine serum albumin (BSA).                               You add 1 mL of the 0.75 mg/mL BSA solution into a standard cuvette (1 cm path length), set your spectrophotometer to 280 nm and read the absorbance of this BSA solution.   Molecular mass of bovine serum albumin = 66.4 kDa. Molar extinction coefficient (e) of BSA = 43824 M-1 cm-1 (at 280 nm).   What absorbance reading will you obtain?

If a powder in a 2gm vial diluted with 6.8ml of diluent provides 8ml of solution and each ml contains 250mg of a drug, how many ml is needed to give 750mg.
