I am a chemistry idiot and I bought this book specifically for practical advice on how to dilute solutions in the laboratory. I was disappointed. This book gives a five-sentence description of Normality (that includes the more-than-obvious joke) and does not provide any examples (such as the difference in calculating the normality of H2SO4 and HCl. Or, how would one calculate the Normality of a 10% H2SO4 solution?) Alas, I remain an idiot.
