Document Summary
If substance is a gas, it is admitted directly to a sample bottle which is separated from the ionization chamber by a small tube system by heating. These electrons knock electrons out of the molecules (or atoms), leaving. R (element isotope) = (constant) x m (element isotope: reference isotope (atomic weight standard) is carbon 12 (12. 0000 g/mol, when determining mole ratios in empirical formulas: o o o. If x. 4 multiply by 5: dilutions, m1v1 = m2v2, know these polyatomic ions, nh4, oh, cn, no3, so4. Chapter 5: avogadro"s hypothesis: equal volumes of different gases, at the same temperature and pressure, contain the same number of gaseous molecules, ideal gas law, pv = nrt o (can be rewritten as) pv = grt / mw. Mw = drt / p: combined gas law, p1v1n2t2 = p2v2n1t1. shift to higher speeds as t1 increases to t2. Area under curve is preserved: at same temperature but different masses (see diagram):
