NOT! Star-Nosed Mole
Amadeo Avogadro • Created the “counting unit” for atoms. • Avogadro’s Number • 6.022x1023 • 1mol = 6.022x1023
Moles Measure Elements • 1mol Carbon-12 = 6.022x1023atoms of Carbon-12 • 1 mol Carbon-12 = 12.000000g • 1 mol Carbon-14 = 14.000000g • 1 mol C (in nature) = 12.0107g • Why?
More Moles • 1 mol Li = 6.941g = 6.022x1023atoms Li • 1 mol N = 14.00674g = 6.022x1023 atoms Li • How many grams of Na in 1 mol Na? • How many atoms of Hydrogen in 1.00794g H ?
Conversion • How many atoms of Mg in 13g of Mg ?
