CALCULATIONS BASED ON FORMULAE 7.5 - Calculations involving Avogadro's number 7.5.3 - Mass in grams to number of particles conversion. Whenever you want to convert quantities from one unit to another, you need to use the appropriate conversion factor. The conversion factor must have units of the two quantities involved The number of particles present in one mole (i.e. 6.023 x 10 23 particles) is called Avogadro's number or Avogadro's constant. Try the following questions: Q. Distinguish between atoms and. 1 Bond types; 2 Examples of bonds; 3 Types of particles; 4 Compounds. 4.1 Primordial Compounds (created before time, and normally have simple and not very arbitrary effects and formulas. Primdorium Theta is not recognized by User:08dravennew due to being arbitrary.) 4.2 Semi-Primordial Compounds (created after time, but have properties similar to Primordial Compounds This is a key formula as the velocity of the particles is what determines both the diffusion and effusion rates. Below is a problem examining the ratio of the velocities for two different molecules at the same temperature. pressure, and the number of particles). To this end we start out with a few assumptions (f) distinguish isotopes based on the number of neutrons present, and state examples of both stable and unstable isotopes. 1.2 Relative atomic, isotopic, molecular and formula masses. Candidates should be able to: (a) define the terms relative atomic mass, Ar, relative isotopic mass, relative molecular mass, Mr, and relative formula mass based. Purpose: Molar mass, also known as formula mass, is the amount of mass of any substance that contains exactly one mole (6.02x10 23) of particles. Before students can begin learning how to use molar conversions, they need to be able to accurately calculate the molar mass of any given compound or element
