How do you find equivalent weight of a metal in a compound?

The equivalent weight of an element is its gram atomic weight divided by its valence (combining power). Some equivalent weights are: silver (Ag), 107.868 grams (g); magnesium (Mg), 24.312/2 g; aluminum (Al), 26.9815/3 g; and sulfur (S, in forming a sulfide), 32.064/2 g.

How do you find the equivalent weight of a compound?

Additionally, the equivalent weight of a compound can 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 do you calculate the atomic mass of a compound?

It’s easy to find the molecular mass of a compound with these steps:

1. Determine the molecular formula of the molecule.
2. Use the periodic table to determine the atomic mass of each element in the molecule.
3. Multiply each element’s atomic mass by the number of atoms of that element in the molecule.

How do you calculate metal weight?

Once you have the measurements for the sectional area, length and density of your metal, you can now determine the weight using the following metal weight calculation formula: Weight (kg) = Sectional Area (mm2) x Length (m) x Density (g/cm3) x 1/1,000.

What is the formula of equivalent?

To calculate the Gram Equivalent Weight, we use the formula Eq = MW / n. Here we will learn how to calculate the Equivalent Weight Formula of a compound. If the mass of a chemical entity is g grams, then the given mass contains gram equivalents given by valency factor× moles.

How do you calculate the weight of an element in a compound?

To calculate the mass percent of an element in a compound, we divide the mass of the element in 1 mole of the compound by the compound’s molar mass and multiply the result by 100. Created by Sal Khan.

What is equivalent and equivalent weight?

The key difference between gram equivalent and equivalent weight is that gram equivalent describes that the mass of one equivalent is given in the unit of gram whereas equivalent weight describes the mass of one equivalent in any unit of measurement.

What is equivalent weight number?

The equivalent weight of an element or radical is equal to its atomic weight or formula weight divided by the valence it assumes in compounds. The unit of equivalent weight is the atomic mass unit; the amount of a substance in grams numerically equal to the equivalent weight is called a gram equivalent.

What is the weight of metal?

specific weight metal and alloy

metal or alloy	weight (kg/dm3)
rolled and drawn brass	8.43 – 8.73
lead	11.34
platinum	21.4
copper	8.93

What is the equivalent weight of a metal in different compounds?

The equivalent weight of a metal in different compounds are 18.6 28 . Atomic mass of the metal would be: The equivalent weight of a metal in different compounds are 18.6 28.

What is the equivalent mass of an element?

Equivalent mass, as said earlier, depends upon the valency of the element. The formula to calculate the equivalent mass of an element is given by Equivalent Mass = Atomic Mass Valency.

What are the elements by atomic number and weight?

The Elements, sorted by Atomic Mass Atomic Number Symbol Name Atomic Weight (amu, g/mol) 1 H Hydrogen 1.00797 2 He Helium 4.00260 3 Li Lithium 6.941 4 Be Beryllium 9.01218

What is equequivalent weight in chemistry?

Equivalent weight predicts the mass of a substance that will react with one atom of hydrogen in an acid-base analysis such as a titration. You can calculate it easily, as long as you know the molecular weights of the compounds involved in the reaction.
