Nthis example we will use the quantization of charge to determine the number of excess electrons in an object. (a) a large plastic block has a net charge of −1.0μc=−1.0×10−6c. how many more electrons than protons are in the block? (b) when rubbed with a silk cloth, a glass rod acquires a net positive charge of 1.0 nc. if the rod contains 1.0 mole of molecules, what fraction of the molecules have been stripped of an electron? assume that at most one electron is removed from any molecule.

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.
