What is the formula of equivalent mass?
The equivalent masses of acids, bases, and salts are calculated as follows: Equivalent mass of an acid = molecular mass of the acid/basicity. Equivalent mass of a base = molecular mass of the base/acidity. Equivalent mass of a salt = molecular mass of the salt/total positive valency of metal atoms.
What is the equivalent mass of NaCl?
58.44 g/mol.
Therefore, the equivalent weight of sodium chloride (NaCl) is 58.44 g/mol.
How do you find the gram equivalent weight of NaOH?
Eq = 98.08 / 2 = 49.04 g/eq. The gram equivalent weight of H2SO4 is 49.04 g/eq. Only half as much sulfuric acid than, for example, HCl, is needed to react something with an acid. The gram equivalent weight of NaOH is 40.00 g/eq.
What is equivalent weight of magnesium?
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.
What is the equivalent mass of al2 so4 3?
An element’s equivalent weight can also be given as the amount that displaces or combines with 1.008 g of Hydrogen or 8.0g of Oxygen or 35.5g of Chlorine. Hence the equivalent weight of $ A{l_2}{(S{O_4})_3} $ is 57 g/mol.
What is the molar mass of NaOH if its equivalent mass is 40?
Determining the Molar Mass of a Compound The molar mass of the compound NaOH is 40 g/mol.
What is magnesium equivalent?
What is the molar mass of SO4?
96.06 g/mol
Sulfate/Molar mass
What is the molar mass of NH4 2HPO4?
132.06 g/mol
Diammonium phosphate/Molar mass
What is N 10 NaOH?
N means normality, one normal of NaOH solution contains 23+16+1=40 grams. ( gram molar mass) of NaOH therefore, N/10 equals 40/10=4 grams. So, add four grams of sodium hydroxide to one litre of water then the N/10 NaOH solution is prepared.
