WebThe definitive way to measure molecular size is X-Ray crystallography. This gives you the structure of the crystal including the positions of all the atoms, so you automatically get the molecule size. This method works for any material that you can crystallise even including huge molecules like DNA and proteins. WebKeep in mind, however, that atoms and molecules, just like everything else in the universe, exist in three dimensions—they have length and width, as well as depth. In the …
Web1 mol = 6.02 x 10^23 1 mol = 22.4 L 1 mol = molar mass in grams Avogadro's law is mostly used for converting from one unit to another so the constant will depend on what you are converting. What it does require is that you use the correct unit of measurement. For example, you have to use liters, you can't use milliliters. WebAssumptions of the kinetic-molecular theory: Gases consist of very large numbers of tiny spherical particles that are far apart from one another compared to their size. Gas particles are in constant rapid motion in random directions. Collisions between gas particles and between particles and the container walls are elastic collisions.
