The mole (symbol mol) is the unit of amount of substance in the International System of Units (SI). The quantity amount of substance is a measure of how many elementary entities of a given substance are in an object or sample. The mole is defined as exactly 6.02214076×10 elementary entities. Depending … See more Nature of the particles The mole corresponds to a given count of particles. Usually the particles counted are chemically identical entities, individually distinct. For example, a solution may contain a certain … See more The history of the mole is intertwined with that of molecular mass, atomic mass units, and the Avogadro constant. The first table of standard atomic weight was published by See more Like chemists, chemical engineers use the unit mole extensively, but different unit multiples may be more suitable for industrial use.

WebParts per million is the molar mass, volume or mass ratio between the pollutant component and the solution. ppm is defined as ppm = 1,000,000 c / s = 106 c / s (1) where c = molar mass, volume or mass of the solute component (mole, m3, ft3, kg, lbm) s = molar mass, volume or mass of the solution (mole, m3, ft3, kg, lbm) WebYou must first find the number of moles which is the mass in grams divide by the molar mass of HCl which would be 36.45g/mole. (1g/mole is Hydrogen and 35.45g/mole is Cl) You get that answer then you divide by your volume in litres, which is 0.5L. Your answer's unit will mol/L which is sometimes also known as just M.
