A grain in weight (0.06gm) of this powder is dissolved in 500 drops (30ml) of 20% alcohol making a 1:500 dilution of the 0.06gm of 3c, and one drop of this solution is then further diluted in 99 drops of 95% alcohol, filling two thirds of a glass vial, giving a (1 in 500 x 100 = 50,000) solution of the 3c powder.

To prepare a standard solution of Zn2+ you first dissolve a 1.004 g sample of Zn wire in a minimal amount of HCl and dilute to volume in a 500-mL volumetric flask to make the stock solution. Next, you dilute 2.000 mL of this stock solution to 250.0 mL.

1. Ensure good ventilation when diluting or using bleach. 2. Put on protective gear (gloves, lab coat or plastic apron, and goggles (recommended) when diluting or using bleach. 3. Cold water should be used for dilution as hot water decomposes the active ingredient, sodium hypochlorite, rendering it ineffective. 4.

Using a 4.0 M solution of MgSO4 , determine how to make 300 mL of a 1.7 M dilution. If you dilute 174 mL of a 1.6 M solution of LiCl to 1.0 L, determine the new concentration of the solution. One liter of a solution is prepared by dissolving 125.6 g of NaF in it. If I took 180. mL of that solution and diluted it to 500. mL, determine the ...

For example, a 1:2 serial dilution is made using a 1 mL volume of serum. This expression indicates that 1 mL of serum is added to 1 mL of H20 and then mixed. This initial dilution is 1:2. Then, 1 mL of this dilution is added to 1 mL of H20 further diluting the sample. This same process is continued.

In other words, make a 1 to 10 dilution of the dilution you just made in the 5 ml beaker. Again prepare a test tube with exactly 3 mL of this new dilution. d) Repeat this serial dilution technique three more times; Each time use the latest made solution (always in a 50 ml beaker) as the solution you take 1 ml out of.

Combined with the molar mass of a solute, Equation 1, used to calculate the number of grams of solute needed to prepare a given volume of a solution with a specific concentration. For example, consider the preparation of 500.0mL of a 0.80M solution of sodium chloride: Grams of NaCl= 500.0mL x 1L x 0.80moles NaCl x 58.5 g NaCl = 23 g NaCl
