- Help please. MD ordered morphine SO4 gr 2/5 and the pharmacist has a stock solution of gr 1/8 per milliliter of morphine SO4. How many milliliters of the stock solution is required to fill the Rx?Concentrations in biochemical systems are often very dilute. Consequently, scientific notation and logarithms are often used to express concentrations. In scientific notation, numbers are expressed as coefficient x 10" To convert a number to scientific notation, proceed as follows: 1. Move the decimal place so that there is one digit in front of the decimal. 2. Account for the moved decimal in the value of x. If the decimal moved to the right, x is negative; if it moved to the left, x is positive. A logarithm is basically an exponent. Unless otherwise indicated, a logarithm is the a of 10". The numbers after the decimal point are significant; the number before the decimal just identify the location of the decimal point for the number. Notice that it is easy to estimate a logarithm from scientific notation; it's the exponent! Logarithms are commonly used to express the concentration of H. The pH is defined as pH= log (In), where the base number is 2.303. The same general rules as logs…> Dimensional Analysis Practice Worksheet.docx nalysis Practice Worksheet.docx mal Analysis Practice Worksheet.docx (13.5 KB) Page 1 > of 2 ZOOM 1.

How many milliliters of the stock solution is required to fill the Rx?III. Problem solving. Show your computations. Answer questions briefly. A 50.0 ml juice extract is colorimetrically assayed using Nelson's test. One milliliter (1.00 mL) of the solution and the standard glucose solution (concentration: 1mg/mL) were treated with freshly prepared Nelson's reagent and arsenomolybdate reagent and then diluted to 10.0 mL separately in properly labeled test tubes. Absorbance at 480 nm for the standard is 1.702 and for the sample, 0.926. A. What is the principle behind the assay?These are SIM media. What does SIM stand for?
