Document Summary
Chem 101: the true meaning and definition of density, molarity, and. Many of you may think, well density is just mass divided by volume , but that is only part of the definition. In fact, from here on out defining density as. Mass over volume will often times get you the incorrect solution. In more specific chemistry terms, density of a molecular substance is defined as d = Pmw/(rt) where d is density, p is pressure, mw is the molecular weight of the substance, r is a constant of . 08206 (atm*l)/(k*mol), and t is the temperature in the si unit of temperature kelvin ( k). In chem 101, we mainly deal with gases and aqueous solutions. For finding the density of a gas, we use the above formula. If it is solid or aqueous then we use the formula you are used to seeing m/v where.
