- In this video, we are going to perform serial dilution calculations. We will solve a practice problem related to serial dilution. Here's the question:
Starting with 5 mg/mL and using a total volume of 10 mL at each step, calculate the final concentration after a 3-step serial dilution at 1:10.

Thank you! I was close to being burnout but learning and understanding how to use DF gave me a new surge of energy. Your video was actually the 10th I've watched to learn serial dilution. Thank you so much!
Could you please make a video on using calibration curve/line regression to find the value of an unknown concentration with absorption? I haven't found a video that I understood well and all of them always seem to skim past what values to use to calculate the slope of the line when it isn't given.
Thanks for taking the time to leave this comment. I'm so glad the video helps. Thanks for the request. However, I'm pausing on releasing new videos at the moment but I'll add your request to the list though. All the best with DF!
this was actually soo helpfull, i was almost certain that i wouldnt be able to find a video about this calculation... Thank you soo much!
I'm glad you find the video helpful. Do share it with anyone that needs it. 😊
Thank you sooo much again. I can finally finish my biochem lab quiz!
You're welcome. Glad the video helps!
Cheers , nicely set out
Thanks! I appreciate that.
Thanks for the explanation. What if we do not know the concentration of the stock solution?
You're most welcome. If you're asked to find the final concentration and is not given the concentration of stock solution, then you should be given information on how the stock solution was prepared. For example, 200 mg of solute was dissolved in sufficient deionized water to produce a 100mL solution. In this case, the concentration will be 2mg/mL. Hope this helps.
@@ChemSimplified Thanks :')
My pleasure!
What is intermediate concentration strength required for 1 in 5 dilution from 40 % w/v to make desired concentration 5 %w/v
is there any formula for this? as I need to dilute until 21 tubes
You can create a worksheet on excel to auto calculate for you using the dilution formula.
Best video but I can't understand cuz I am in 3rd standard 😅😅😅
Thank you! No worries. I hope I'll be able to accompany you in your Chemistry journey. 😊
@@ChemSimplified 👍👍👍
A 200 mg concentration is diluted 1:20 , and further diluted to 1: 5, then what is the final concentration?
(200*1)/20 = 10
(10*1)/5 = 2
2mg Per whatever volume
