Equivalent weight of br2?
Verified Answer
Equivalent weight of br2?
Equivalent weights may be calculated from molar masses if the chemistry of the substance is well known: sulfuric acid has a molar mass of 98.078(5) g mol−1, and supplies two moles of hydrogen ions per mole of sulfuric acid, so its equivalent weight is 98.078(5) g mol−1/2 eq mol−1 = 49.039(3) g eq−1.

Equivalent weight of br2?
Equivalent weight of Br2
The equivalent weight of a substance is defined as the mass of the substance that combines or reacts with one equivalent of the reacting species. In the case of Br2, which is a diatomic molecule composed of two bromine atoms, the equivalent weight can be determined based on its molar mass and the number of equivalents.
Molar mass of Br2:
The molar mass of Br2 can be calculated by adding the atomic masses of two bromine atoms. The atomic mass of bromine (Br) is approximately 79.904 g/mol. Therefore, the molar mass of Br2 is:
Molar mass of Br2 = 2 × Atomic mass of Br = 2 × 79.904 g/mol = 159.808 g/mol
Definition of equivalent weight:
The equivalent weight is the molar mass of a substance divided by the number of equivalents. In the case of Br2, which is a diatomic molecule, the number of equivalents is equal to the number of moles of Br2.
Calculating the number of moles of Br2:
To calculate the number of moles of Br2, we need to know the mass of the substance. Let's assume we have a sample of Br2 weighing 'x' grams.
Number of moles of Br2 = Mass of Br2 (in grams) / Molar mass of Br2
Calculating the equivalent weight of Br2:
Once we have the number of moles of Br2, we can determine the equivalent weight by dividing the molar mass of Br2 by the number of moles.
Equivalent weight of Br2 = Molar mass of Br2 / Number of moles of Br2
Example:
Let's consider an example where we have a sample of Br2 weighing 31.976 grams.
Number of moles of Br2 = 31.976 g / 159.808 g/mol = 0.2 mol
Equivalent weight of Br2 = 159.808 g/mol / 0.2 mol = 799.04 g/equivalent
Therefore, the equivalent weight of Br2 is 799.04 g/equivalent.
Summary:
The equivalent weight of Br2 can be calculated by dividing its molar mass by the number of moles of Br2. The molar mass of Br2 is determined by adding the atomic masses of two bromine atoms. The number of moles of Br2 can be calculated by dividing the mass of the substance by its molar mass. Finally, the equivalent weight is obtained by dividing the molar mass by the number of moles. In the example provided, the equivalent weight of Br2 was found to be 799.04 g/equivalent.
