Which electrostatic potential map corresponds to F2C O, and which to H2C O?
Wednesday, January 27, 2016 Moles, Conversions, Avogadros Number Chapter 3 Introduction to the Mole Concept - The periodic table shows the wighted average mass of an element, which means that the relative abundance of isotopes are taken into consideration • H —> 1.008 amu • C —> 12.01 amu • Fe —> 55.847 amu - How do we measure these • Common lab balances measure in grams, not amu - Remember, 1 amu = 1.66053873 x 10^-27 Avogadro’s Number - H —> 1.008 amu • 1 amu = 1.6605 x 10^-27 kg - Diatomic molecules will be 2 x 6.022x10^23 • Which are not atoms anymore but molecules Mole (mol) - Mol: Amount of substance that contains as many basic particles as there are atoms in exactly 12 g of C-12 •
