Determination of concentration of an unknown sample (Tutorial)

In this tutorial, you will learn to determine the concentration of an unknown sample by calibration curve of known sample or standard compound. I perform this tutorial in Excel 2019 on Windows 10.

How did you open up (Format Trendline) at 00:40 ??

[divyapawar]

Really helpful video..many of the videos do not explain how the value of equation is obtained but u have explained it step by step thank u so much

[falgunibarman]

This is what, I just waiting for. Thank you madam😁

[Aralynia]

Thanks for this video, it really saved my late night studying!

How to calculate from removal efficiency ?

[nidhitiwari]

When unknown sample diluted upto 100 times, then how we incorporate dilution factor into the concentration..
Is their is any formula to calculate the concentration of unknown??

[anandrsaraf]

Thanks for sharing... very nice explained

=trend( conc, absorbance, absorbance of unknown conc)
How can we select this ?.. because when I select one, the other get deleted

Mam I have Doubt in how its calculating Unknown Concentration value, and R square Value, y also
share the Formula mam

[anjalisharma]

Please tell the finding unknown concentratiin by beer Lambert law also

[rameenfatima]

What is R that is giving the value 0.9945??

[glicyloud.garinggo]

Thanks for this! Just wanna ask where did you get the absorbance of an unknown sample. Is it given in the problem or what? Thanks.

[cpjjgzj]

if rsquare value is 0.90
can it considered correct?

[shreyathakur]

Reading khin v aaye graph straight hi bnana h?

[anjalisharma]

How can we know the absorbance of unknown sample?

[raktimroy]

I am not finding how to find add trendline option

[shaifasaleem]

you are selecting x axis value 1st and then y axis value, , while in formula there is option to enter y axis value 1st. kindly recheck your method

Apne 0.76 kaha se liya pura confused ho gya waha pe
