- How many mL of solvent do you need to add to the amount gotten from the 2M Palmitic acid stock solution in order to prepare 250 mL total volume of your desired solution? Final answer must be rounded off to 2 decimal places, and shall NOT have any units.pneumonia is characterized by fever (a body temperature) does the patient have a body temperturr that indicates that he has pneumonia? justify your answer with suitable caculation PLEASE.pneumonia is characterized by fever (a body temperature) does the patient have a body temperturr that indicates that he has pneumonia? justify your answer with suitable caculations.
- What's the differences between two questions? Q1) How much calcium would you ingest by drinking one 8 oz glass of your tap water? Show all calculations. -->Tap water 8Oz = 8 x 0.0296L = 0.2368L Hardness = 66.73ppm = 66.73mg/L CaCO3 1L has 66.73mg CaCO3 0.2368L has 66.73mg x 0.2368 = 15.8017mg MW of CaCO3 = 100g/mol MW of Ca = 40g/mol 100g CaCO3 has 40gf of Ca 15.8017mg CaCO3 has 40/100 x 15.8017mg Ca We would ingest 6.321mg of Ca. Q2) What percentage of the recommended daily dose of calcium (1,150 mg/day) does 1.0 L of your water provide? Show all calculations. --> 66.73mg/1150mg x 100 = 5.80% My Question) Why this calculation is wrong? I think this calculation is same with question 1. Isn't it? CaCO3 = 100g/mol, Ca = 40g/mol 100g CaCO3 has 40g Ca. 66.73 CaCO3 has 40/100 x 66.73mg Ca Ca = 26.70mg 26.70mg/1150mg x 100 = 2.32%4. A fat sample with combination of acids contain standard hydrochloric acid for blank and sample with 8mL and 5mL respectively. The normality of the standard hydrochloric acid is 0.93N and the weight of the sample is 3 grams. Calculate the saponification value.If a pharmacist adds 3g of hydrocortisone (HC) to 60 g of a 5% (w/w) hydrocortisone cream, what is the final percentage strength of hydrocortisone in the product. Hint: identify first the amount of HC present in 60 grams then add the 3 grams to both the amount of solute and solution then compute for the new percentage. Answer has 2 decimal places.
- State the average concentration of your NaOH solution, as determined using your two determinations (the "best two", if applicable). Report your answer to the correct number of significant figures and include any applicable units.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. Standard Volume of stock B2- solution taken, mL Molarity of dilute B2 Construct a graph of Absorbance vs. molarity of B2- in Excel using the data in the preceding table. Make certain to title the graph and include axes labels with proper units. Absorbance is dimensionless (has no unit). Add a linear trendline to the graph but do not set the y-intercept to zero Solid M2B is added to 25 mL of water, the resulting mixture is continually stirred for 1 hour. At this point, it is assumed that equilibrium (eqn 3) has been established. The mixture is transferred to a test tube, and the test tube is centrifuged to assure that any residual solid M2B is fully settled out. A portion of the supernatant in the test tube is carefully…The standardized basic solution (0.0939 M) was then used in getting the total acidity of a food sample. 10 mL of the acidic sample consumed 10.3mL in the first trial then 10.0mL in the second trial to reach endpoint. Determine the normality of the acidic sample.
- A solution of potassium phosphate contains a mixture of 164 mg of monobasic potassium phosphate (MWt: 136) and 158 mg of dibasic potassium phosphate (MWt: 174) per milliliter. If a hyperalimentation fluid calls for the addition of 45 mEq of potassium, how many milliliters of the solution should be used to provide this level of potassium? How many millimoles of total phosphate will be represented in the calculated volume of potassium phosphate solution?Stock iron(II) solution (200Ug mL-1 Fe) ferrous ammonium sulfate hexahydrate mass= 0.1437g, transfer it to a 100 ml beaker. add 15 ml approx of water and 15m1 'approx of dilute sulphuric acid (2M H2SO.). then transfer FeII to 100 ml flask makeup to the mark with water. calculate the moles of ferrous ammonium sulfate hexahydrate solution in unit ug/mL.The mass of a beaker is 5.333g.
