Converting moles to grams Study guides, Class notes & Summaries

Exam (elaborations) GIZMO Moles, Avogadro, and Molar Mass 1. In the image, note a dozen eggs, a dozen donuts and a dozen roses. How many of each item do you have? 12 eggs, 12 donuts, and 12 roses. 2. Would a dozen of each object have the same mass? No 3. Suppose you have a dozen silver atoms, a dozen oxygen atoms, and a dozen lithium atoms. Even though you have the same number of each, will they all have the same mass? Explain. They will not all have the same mass because although the...

atomic number - ANSWER The same as the number of protons in the nucleus of an element; it is also the same as the number of electrons surrounding the nucleus of an element when it is neutrally charged. mass number - ANSWER The sum of an atom's neutrons and protons isotopes - ANSWER Atoms of an element with different numbers of neutrons Avogadro's number - ANSWER 6.022×10²³ particles per one mole Moles - ANSWER grams/molar mass Standard Temperature and Pressure (STP) - ANSWER ...

CHEM 103 MODULE 3 NOTES. 3.1: THERMOCHEMISTRY Thermodynamics is the study of the relationship between heat and other forms of energy, particularly mechanical work. Thermochemistry is the part of thermodynamics that deals with the quantity of heat given off or absorbed during a chemical reaction. The quantity of heat given off or absorbed during a physical change or temperature change can also be studied, and we will refer to this process as calorimetry. In order to adequately discuss thermoch...
