Quantitative Analysis Cheat Sheet
Chapter 1: Measuring the amount of substance
Analytical chemistry: science of chemical measurement. Its object is the generation, treatment and evaluation of signals from which information is obtained on the composition and structure of matter
Measurement: process of obtaining the magnitude of a quantity
Example: The amount of saturated fat in the sample is 3 g/serving.
Quantity: attribute of a phenomenon that may be distinguished qualitatively and determined quantitatively
Value: magnitude of a particular quantity expressed as a unit of measured * a number
Unit: particular quantity defined and adopted by convention for comparison of magni
Globalization requires comparability of measurements
Metric system: Meter Convention led to the signing of the Meter (1875) establishing the Bureau International des Poids et Measures
In 1960, the 11th General Conference on Weights and Measures adopted the name Systeme International d’Unites (ISU) for recommended practical system of units of measurement
Fundamental SI units: length (m), mass (kg), time, electric current (a), temp, luminous intensity – candela (cd), amount of substance (mol), plane angle (radian), solid angle (steradian)
Meter: from 1/1x10^7 distance from equator to north pole distance travelled by light in a vacuum in 1/299, 792, 458 second
Kg: only remaining unit whose definition is based on an international prototype Prototype 52 (Germany) 18 (UK) 20 (US) International proto (Sevres, France) 90% Pt, 10% Ir alloy
SI derived: frequency(1/s), force, pressure (pascal), work, power (watt), charge (coulomb), electric potential (volt), elec resistance (ohm)
24-(-24) yotta, zetta, exa, peta, tera, giga, kilo, hector, deka, deci, centi, milli, micro, nano, pico, femto, atto, zepto, yocto amount of substance: number of some specified elementary entity: mole (quantity: amount) unit: mole
