Explain how to prepare the following in a chemical lab:
Prepare a set of four standards in 2mL sample vials:
1-0% biodiesel, 2-10% biodiesel, 3-20% biodiesel, 4-30% biodiesel in diesel by volume. After the standards are made in the correct ratios, dilute them to 1/20^th of their original concentration in octane.

Solutions

Expert Solution

Answer:-

For 1-0 % of the biodiesel solution we have to dissolve 20 microlite of Biodiesel in the vial and make up the volume to 2ml.

For diluting it to 1 / 20th of original concentration in octane we have to take 1 part of the 1% solution and 19 part of the octane that will gives 1 / 20th dilution of it.

For 2-10%if we are taking the upper limit i.e 10% 0.2ml of Biodiesel in the vial and make up the volume to 2ml.

For diluting it to 1 / 20th of original concentration in octane we have to take 1 part of the 10% solution and 19 part of the octane that will gives 1 / 20th dilution of it.

For 3-20%if we are taking the upper limit i.e 20% 0.4ml of Biodiesel in the vial and make up the volume to 2ml.

For diluting it to 1 / 20th of original concentration in octane we have to take 1 part of the 20% solution and 19 part of the octane that will gives 1 / 20th dilution of it.

For 4-30%if we are taking the upper limit i.e 30% 0.6ml of Biodiesel in the vial and make up the volume to 2ml.

For diluting it to 1 / 20th of original concentration in octane we have to take 1 part of the 30% solution and 19 part of the octane that will gives 1 / 20th dilution of it.

How do I prepare the four standards? Materials Methanol 200. ppm w/v nicotine stock in methanol 250. ppm w/v quinoline stock in methanol Standard Preparation Prepare four standards using methanol as the dilution solvent. These standards should be prepared directly in GC vials assuming additivity of all solutions (use micropipets). The final volume of each should be 1.00 mL. The nicotine concentration should vary as follows: 10.0, 20.0, 30.0, 40.0, and 50.0 ppm w/v. The quinoline concentration should be 25.0...
