Some polymers have unusual properties. For example, Kevlar (3) is strong enough to be the material of choice for bulletproof vests and is stable at temperatures up to 600K. What molecular interactions contribute to the formation and thermal stability of this polymer?

Chapter3: The Mole& Stoichiometry Monday, September 26, 2016 The mole o 1 mole (mol) of atoms = 6.0221423 x10 atoms *Avogadro’s number - 12 1 mol of C has a mass ofexactly12g This is a very 1 mol of C has a mass of12.0107g important number get 1 mol of O has a mass of15.9994g comfortable using it!!! You’ll justbe expected Molecular Mass (aka Molecular Weight) 23 o 1 mol of H 2olecules has 2times 1 mol of H atoms to use 6.022 x10 H 2 2x 1.00794g =2.01588g most of the time This number represents This number came from how many atoms you the periodic table have of a specific element o Formula Mass canbecalculatedthe sameway i.e.CaCl2,PCl5,NaI o Example: What is the molar mass of sugar(C 6 12)6 C = 6x (12.01g) Add thesetogether to H =12 x (1.0079g) O = 6 x(15.999g) getmolar mass (g/mol) 180.155 g/mol What is the mass of 0.350 mol of sugar - *Molar Mass inmost problems will be your conversi
