Robert Boyle Robert Boyle Robert Boyle (; 25 January 1627 – 31 December 1691) was an Anglo-Irish natural philosopher, chemist, physicist, and inventor. Boyle is largely regarded today as the first modern chemist, and therefore one of the founders of modern chemistry, and one of the pioneers of modern experimental scientific method. He is best known for Boyle's law, which describes the inversely proportional relationship between the absolute pressure and volume of a gas, if the temperature is kept constant within a closed system. Among his works, "The Sceptical Chymist" is seen as a cornerstone book in the field of chemistry. He
Molar volume Molar volume The molar volume, symbol "V", is the volume occupied by one mole of a substance (chemical element or chemical compound) at a given temperature and pressure. It is equal to the molar mass ("M") divided by the mass density (ρ). It has the SI unit cubic metres per mole (m/mol), although it is more practical to use the units cubic decimetres per mole (dm/mol) for gases and cubic centimetres per mole (cm/mol) for liquids and solids. The molar volume of a substance can be found by measuring its molar mass and density then applying the relation If the
