The equivalent weight of an element is its atomic weight in grams 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, forms a sulfide), 32.064/2 g.
How is equivalent weight in grams calculated?
the equivalent in grams is the number of equivalents. while the equivalent weight in grams is the mass of equivalents.
What is the difference between gram equivalent and weight equivalent?
the equivalent in grams is the number of equivalents. while the equivalent weight in grams is the mass of equivalents.
What is 1 gram equivalent?
We can define equivalent mass in grams as the mass of one mole of an element, ion, or molecule divided by their shared electrons or valences.
How do you find an equivalent weight?
The equivalent weight of an element or a radical is equal to its atomic weight or formula weight divided by the valence it occupies in compounds. The unit of equivalent weight is the atomic mass unit. The amount of a substance in grams that is numerically equivalent to the equivalent weight is called the gram equivalent.
What is the gram equivalent weight of HCl?
The equivalent weight of an acid or base for neutralization reactions, or any other compound acting by double decomposition, is that amount of the compound which yields or reacts with or is equivalent to 1.008 g hydrogen ion or 17.0074 g hydroxide ion, e.g. , hydrochloric acid (HCl), 36.461 g sulfuric acid …
What is the equivalence formula?
Equivalent weight calculations in grams Eq = unknown. MW = 127 g/mol. Look at a periodic table and find the atomic masses of H, P and O in g/mol: H = 1.01 O = 16.00 P = 30.97, Add the masses for H 3 PO 4: 3 × 1.01 + 30.97 + 4 × 16.00. 01 = 127 g/mol.
What is the equivalent weight of oxalic acid?
Equivalent mass of oxalic acid = molecular mass of oxalic acid/2 = 126 g/2 = 63 grams. Therefore, the equivalent weight of oxalic acid is 63 grams.
How much is 1g?
