Hellora everyone,

I'm building a benzene calibration curve starting from a initial standard benzene with a 1.54 ppm in triacetine

The curve will be
1 point diluted 1/40
2 point diluted 1/4
3 point diluted 1/1
4 point not diluted

I would like to ask you how can i calculate the concentration taking into account the weight of std weighted on balance and the purity of the std

Thanks in adavance
