CHEM 1150 Lecture Notes - Lecture 1: Microgram, Kilogram, Picosecond
Document Summary
Chemistry is a scientific field; hoping to understand why matter is the way that it is on a molecular level. (understanding the macroscopic world through the microscopic). Scientific method: a way of problem solving, involving the recognition and formulation of a problem, and collection of data through different methods. However, it is especially important to use standard measurements, so that others may understand your data. In chemistry this system of standard measurements is called the si unit system. here are the basic units. A derived unit is a unit of measurement that is taken from one of the 7 base si units. A derived unit is : speed, volume, density: Example: a piece of metal is found to have a mass of 13. 4 g and a volume of 4. 998 . Using the table below determine the possible identity of the metal. Sometimes, the numbers used in chemistry are very large or extremely tiny.
