How often are Chemistry students amazed to find as much math as they do in their first week of General, Organic & Biology Chemistry? This manual is designed for them. This friendly guide leads students through early mathematical steps-fractions, percents, scientific notation, into the world of calculators and how to get the most out of them. It progresses, parallel to their classwork, through algebraic problem-solving, into the whole variety of necessary conversions: density, mass, volume; Celsius, Fahrenheit; calories, Joules, BTUs; and molar mass, moles, grams. Applications and down-to-earth examples abound.
