CHEM 101 Lecture Notes - Unified Atomic Mass Unit, Chlorine, Molar Mass
Document Summary
Chlorine mass on periodic table is justthe ofall isotopes. Tom 24. 2 atomic mass is a weighted averageofthese. Chlorine is diatomicthough two isotopes bonded isotopolophs together spa pistane. Simultaneousprobabilityof independentevents pla pcb pcc multiply the each isotope ex. C12 is a reference point getting mass in kg amu o 1. 6603105na mass of atom scaling up from amu. The move use the more of atoms thatmake up 12g pure carbon 12. I mole of anything is 6. 022 1023of that thing. Determine sample of au of atoms in a 100g ex. Themole enables us to use measured mass to count particles. Determine d of nocuous after multiplying g by ofnocuous to gettotal d same mass same 4 ofnucleons of nucleons peratom. Energy measure of a system"s abilitytodowork displace stuff. Potentialenergy energy associated with position or composition heightin m. Ape pefinal negative ape means energy was released in thesystem when energyis released. Ke t pe totalenergy energy is not lost converted to heat uponimpact.
