You can get these values from experiment. I have used imaginary values for demonstration purpose

how do we know that the calibrated graphic that we made is correct sir?

There are multiple factors. Firstly, make sure that your values falls into a linear range. Secondly, the value of correlation coefficient and coefficient of determination is also indicate the accuracy of calibration curve

That is the intercept value. you can get this value from regression equation generated by excel

Please find the unknown concentration without the trend line equation. It's highly advicable not use the equation in most experimental reports

TREND(select the concentration of std.,select the O.D of std.,select the O.D of unknown sample) Do this in excel

Don't use English title for your video if you are not making an english video. It is very cheep when you do a video in your own language and use a title from another languages.

Actually, you are a cheap person. Think before you speak. I am using English language as teaching medium. The people from more than 50 countries are taking advantage from these video. You have a sick mentality
