Molar volyme

In chemistry and related fields, the molar volume, symbol Vm, [1] or of a substance is the ratio of the volume occupied by a substance to the amount of substance, usually given at a given temperature and pressure. It is equal to the molar mass (M) divided by the mass density (ρ). 1 mol formel 2 What is Molar Volume? At standard Temperature and Pressure (STP) the molar volume (Vm) is the volume occupied by one mole of a chemical element or a chemical compound. It can be calculated by dividing the molar mass (M) by mass density (ρ). Molar gas volume is one mole of any gas at a specific temperature and pressure has a fixed volume. 3 2 mol 4 Molar volume is the volume of one mole of a substance at a specified pressure and temperature. It is commonly denoted by the symbol V m. Units The SI unit of molar volume is cubic meters per mole (m 3 /mol). However, because that is such a large volume, other units are usually used. 5 Molar volume Vmol (sometimes noted only by V) is the volume occupied by 1 mol of a compound (or element) at a given temperature and pressure. The expression for Vmol is given by the formula: () V mol = M w ρ In expression (), Mw is the molecular weight and ρ is the density of the compound. 6 The molar volume of a gas is the volume of one mole of a gas at STP. At STP, one mole ( × × 10 23 representative particles) of any gas occupies a volume of L L (figure below). Figure 3: A mole of any gas occupies L L at standard temperature and pressure (0oC 0 o C and 1atm 1 atm). 7 1 molar 8 Inom kemin är ett ämnes molvolym volymen av en mol av ämnet och anges med symbolen Vm, eller {\displaystyle {\tilde {V}}}. 9 Molar volume is volume divided by. 10
