What is Equivalent Mass?
The mass of a particular substance that can combine with or displace 1 gram of hydrogen or 8 grams of oxygen or 35.5 grams of chlorine, used in expressing combining powers, especially of elements is called the equivalent mass.
For acid–base reactions, the equivalent weight of an acid or base is the mass which supplies or reacts with one mole of hydrogen cations (H+).
For redox reactions, the equivalent weight of each reactant supplies or reacts with one mole of electrons (e−) in a redox reaction.
Equivalent weight has the units of mass, unlike atomic weight, which is now used as a synonym for relative atomic mass and is dimensionless. Equivalent weights were originally determined by experiment, but (so far as they are still used) are now derived from molar masses. The equivalent weight of a compound can also be calculated by dividing the molecular mass by the number of positive or negative electrical charges that result from the dissolution of the compound.
How to Calculate Equivalent Mass of Metal using Hydrogen Displacement Method?
Equivalent Mass of Metal using Hydrogen Displacement Method calculator uses Equivalent Mass of Metal = (Mass of Metal/Mass of Hydrogen Displaced)*Equivalent Mass of Hydrogen to calculate the Equivalent Mass of Metal, The Equivalent Mass of Metal using Hydrogen Displacement Method formula is defined as the mass of metal that displaces 11200 ml of hydrogen at NTP from an acid, alkali or alcohol. Equivalent Mass of Metal is denoted by E.MMetal symbol.
How to calculate Equivalent Mass of Metal using Hydrogen Displacement Method using this online calculator? To use this online calculator for Equivalent Mass of Metal using Hydrogen Displacement Method, enter Mass of Metal (W), Mass of Hydrogen Displaced (Mdisplaced) & Equivalent Mass of Hydrogen (E.MHydrogen) and hit the calculate button.
