It is a matter of convenience which got lost a bit with our improved understanding of science. This relationship between liters and moles holds true at standard temperature and pressure (STP) since both temperature and pressure affect the volume of a gas. However, most chemical equations are written in terms of moles so that the number of atoms of each type balances out on both sides of the equation. Moles for chemists are not only found in gardens but appear everywhere: our mole calculator teaches you everything you need to know about this concept. It measures how much of a substance is dissolved in a given volume of solution. If we need to determine the Molar Mass of a substance, simply divide the given Mass of the Substance by the given number of Moles. In other words, molality is the number of moles of solute (dissolved material) per kilogram of solvent (where the solute is dissolved in). Teresa is a chemistry expert with a PhD in environmental science, a Master's degree in earth, atmospheric, and planetary sciences, and Bachelor's degree in chemistry.
