hey all
i don't understand how to do question 14 a) (completing the table)
for chromatograms, are we supposed to measure the peak heights?
cause if we are, for the 30 ppm peak, i get 4.6cm.
However, the book says that the peak height for 30ppm is 7.4cm
could someone please help

I remember when dekoyl asked this Q.

Answers are 100% wrong.

The books were off by a lot. Obviously they couldn't use a ruler.
