In this regard, how do you prepare a stock solution for serial dilution?

The first step in making a serial dilution is totake a known volume (usually 1ml) of stock and place it intoa known volume of distilled water (usually 9ml). This produces 10mlof the dilute solution. This dilute solution has 1mlof extract /10ml, producing a 10-fold dilution.

Furthermore, how do you prepare concentration of a solution? Method 2 Finding Concentration in Percentage orParts per Million

1. Find the mass of the solute in grams.
2. Determine the total mass of the solution in grams.
3. Divide the mass of the solute by the total mass of thesolution.
4. Multiply your answer by 100 if you want to find the percentconcentration.

Beside above, why are stock solutions prepared?

A stock solution is a concentratedsolution that will be diluted to some lower concentrationfor actual use. Stock solutions are used to savepreparation time, conserve materials, reduce storage space,and improve the accuracy with which working lower concentrationsolutions are prepared.

What is a 1% solution?

A one percent solution is defined as1 gram of solute per 100 milliliters final volume. Forexample, 1 gram of sodium chloride, brought to a finalvolume of 100 ml with distilled water, is a 1% NaClsolution. To help recall the definition of a 1%solution, remember that one gram is the mass ofone milliliter of water.
