A 50X stock has 50 times the concentration of solute as a working solution. For example, an enzyme storage buffer may be used at a concentration of 0.01 M TRIS. This is the working concentration of the TRIS solution (1X). But because of shipping costs, a small amount of the enzyme buffer is shipped as a 10X solution with a concentration of 0.1 ...

The more ions that are present in solution, the more light can be absorbed. As a result, the amount of light that is absorbed (called absorbance) is directly proportional to the concentration of the solution. In other words a graph of absorbance v. concentration will give a straight line.

Your calculator will read 1.02616, but the final answer should be reported as 1.0 g/mL because 25 mL only has 2 significant digits. Showing calculations in your report; ... You will need to calculate the number of moles of reagent from the concentration and volume of solution. Use the molar mass of the solid to calculate the mass to be measured.

standard solution. is a solution of known concentration. Because these standard solutions have high concentrations of iron, the concentration of FeNCS2+ in them is the same as the initial concentration of SCN-. Label six containers. Label a 125 mL Erlenmeyer flask as “Blank”. Label five 50 mL volumetric flasks as “S1” through “S5”.

Whereas there is a very small concentration of potassium in the extracellular fluid, the predominant cation of the intracellular fluid is potassium with an intracellular concentration of 140 mEq/l. The intracellular chloride concentration is very low in most cells. ... Repair solution: 0.9% saline = 1.54 mEq/10 cc = 20 cc/hr x 30 hours.
