I have a problem with task below, hope you can navigate/ help me with it
In a 100 mL measuring flask 30 µL of butan-1-ol is placed by pipetting, The flask is filled to the mark with technical grade acetone,
The solution is analysed once and the following areas are found:
Calculate the concentration (v/v%) of propan-2-ol in the sample, Show the calculations:
What I did until now, I deviated Area of sample / Area of Internal standard (which is butan-1-ol, 0,03% v/v), I know that concentration I should find by drawing standard curve, but how if concentration is not given?
So formula should looks like that: c= (Area of sample/Area of IS - intercept)/slope . but, how to calculate concetration to draw std curve?
Thank you in advance!
