Understand the term ‘isotopes’. Define the terms ‘relative isotopic mass’ and ‘relative atomic mass’ based on the . 12. C scale. Understand the terms ‘relative molecular mass’ and ‘relative formula mass’ including calculating these from relative atomic masses . Know what information they can provide. Interpret simple mass spectra graphs. Know some uses of mass spectrometry. A mass spectrometer….. Draw the mass spectrometer. Describe the 5 step process. AS A CARTOON STORY BOARD!. Atomic Mass. What is an elements atomic mass?. The weighted average of its naturally occurring isotopes. .. When looking at an element on the periodic table of elements, where is atomic mass found?. Usually the top left hand corner of each elements box. However, on the periodic table that you will use for your AP Exam(s), this number will be located below each elements chemical symbol.. Stoichiometry. Mass and Moles of a Substance. Chemistry requires a method for determining the numbers of molecules in a given mass of a substance. . which has lead to the development of the . mole. (quantity of substance to be discussed later).. Up to this point in the course we have treated everything as a single point in space, no matter the mass, size, or shape. We call this “special point” the . CENTER OF MASS. . The . CoM. is basically a coordinate which represents the average position of the mass.. Mass. is the measure of the amount of matter in an object.. Mass and Weight are different. . Weight. is the amount of gravitational force pulling on an object. . Weight can also change from place to place (planet to planet), but mass always stays the same..

Mass is measured with a scale.. English Units vs. Metric Units. English Units – units used in the U.S.. 1 Pound = 16 Ounces. One Loaf = 1 Pound. One slice = 1 Ounce. INDEX. Anthropometry generally refers to measurement of physical attributes of the human body.. It is a vital tool in the identification of physical variations among different humans & races. Body mass index (BMI) is a key anthropometric index . Mass Spectrometry deals with the examination of characteristics fragments and arising from the breakdown of organic molecules. The mass spectrum is the plot of relative intensity of the ions agains Will M. Farr. Northwestern University, CIERA. (See . Kreidberg. , . Bailyn. , WMF, . Kalogera. , arXiv:1205.1805). The Mass Gap.
