Diluting Solution: How to Achieve 1:10 Ratio with 7ml Ethanol and 3.2gm Leaf

[rovaniemi]

Hi all,

I have a problem than I need to figure out.

I have added 7ml ethanol to 3.2 gm leaf(any leaf)

I have been told to dilute the solution to 1:10 ratio. How to do it?

Could you all please help me?

Now you have a solution right? To dilute the solution 10 times, add 10 times the solvent to it...

Close, but wrong. Adding 10 volumes of solvent would dilute the solution 11 times.

Close, but wrong. Adding 10 volumes of solvent would dilute the solution 11 times.

So I believe we have to add 9 times the solvent, sorry for that mistake...

I would recommend the following steps to achieve a 1:10 ratio with 7ml ethanol and 3.2gm leaf:

1. Determine the desired volume of the final solution. For example, if you want a total of 10ml, then you will need to add 3ml of additional solvent (water or ethanol) to the 7ml of ethanol already present.

2. Calculate the dilution factor by dividing the total volume of the final solution by the volume of the original solution. In this case, the dilution factor would be 10/7= 1.43.

3. Measure out 3.2gm of leaf and place it in a clean container.

4. Add 7ml of ethanol to the container containing the leaf.

5. Mix the solution thoroughly to ensure the leaf is fully immersed in the ethanol.

6. Using a pipette or graduated cylinder, add the desired volume of additional solvent (in this case, 3ml) to the container.

7. Mix the solution again to ensure uniform distribution of the solvent.

8. The final solution now has a 1:10 ratio of 7ml ethanol to 3ml additional solvent, resulting in a total volume of 10ml.

It is important to note that the dilution factor may vary depending on the desired final volume and the volume of the original solution. It is always recommended to double-check your calculations and measurements to ensure accuracy in your dilution process. I hope this helps in achieving your desired 1:10 ratio.
