To calculate molar equivalents for each reagent, divide the moles of that reagent by the moles of the limiting reagent: Note that the molar equivalency of sodium benzoate is 1. This is because sodium benzoate is the limiting reagent. Any reagents used in excess will have a molar equivalency greater than one.
What is equivalent factor in medicinal chemistry?
In redox reactions, the equivalence factor describes the number of electrons that an oxidizing or reducing agent can accept or donate. Here, 1/feq can have a fractional (non-integer) value. In precipitation reactions, the equivalence factor measures the number of ions which will precipitate in a given reaction.
What is equivalent number in chemistry?
An equivalent (symbol: officially equiv; unofficially but often Eq) is the amount of a substance that reacts with (or is equivalent to) an arbitrary amount (typically one mole) of another substance in a given chemical reaction.
How do you find the equivalent of a solute?
EW is the equivalent weight in g/equivalent. It is calculated by dividing the molecular weight of solute by the number of equivalents per mole of solute (Equation 2). For acids, the number of equivalents per mole is the number of H+ ions contributed by the acid per mole of acid.
What is equivalent factor?
Equivalent factors are factors used to convert quantities from their original physical units into a common accounting unit for the purpose of aggregating energy sources or assessing contributions” to environmental problems from diverse sources (for example, the contribution of different pollutants to global warming).
What is equivalent formula?
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 equivalent weight of h2so4?
Sulfuric acid has two hydrogen atoms that can be replaced. As a result, Sulphuric acid’s equivalent weight is 49u.
What is equivalent weight of NaOH?
Hence, the equivalent weight of NaOH is 40g/mol.
What is equivalent weight of NaCl?
The equivalent weight of NaCl is 58.5/1 or 58.5.
How do you find equivalent fractions?
To find the equivalent fractions for any given fraction, multiply the numerator and the denominator by the same number. For example, to find an equivalent fraction of 3/4, multiply the numerator 3 and the denominator 4 by the same number, say, 2. Thus, 6/8 is an equivalent fraction of 3/4.
How do you calculate the number of gram equivalents of a solute?
- Normality = Number of gram equivalents × [volume of solution in litres]-1
- Number of gram equivalents = weight of solute × [Equivalent weight of solute]-1
- N = Weight of Solute (gram) × [Equivalent weight × Volume (L)]
- N = Molarity × Molar mass × [Equivalent mass]-1
What is the equivalent weight of na2co3?
= 53 g/eq.
What is the equivalent fraction of 2 by 5?
Equivalent fractions of 2/5 : 4/10 , 6/15 , 8/20 , 10/
What is the equivalent fraction of 2 by 3?
A fraction can have multiple equivalent ones. For example, 2/3 is a fraction equivalent to 8/12, 6/9, 4/6 and so on.
What is the equivalent of 3 6?
3/6 is 3 between 6, which is 0.5.
What is N factor in equivalent mass?
n factor is atomic weight or molecular weight by equivalent weight. n factor for acids is its basicity,ie, no of replaceable hydrogen ion per molecule. HCl has n factor 1 n H2SO4 has 2 H3PO3 has n factor 2 because when H3PO3 dissociates to form H+ and HPO3−2.
How do you know if an equation is equivalent?
What is the equivalent weight of cacl2?
Therefore 55 grams of calcium chloride is the equivalent weigh because 55 grams of calcium chloride would supply one mole of positive or negative charges when dissolved in water.
What is the equivalent weight of HCl?
Now equivalent mass is given as the molecular weight divided by the n-factor. Therefore, the equivalent mass of HCl is 85.1g.
What is the equivalent weight of ch3cooh?
Equivalent mass = Atomic or molecular weight n factor = 60 . 05 1 = 60 . 05 u.
What is the equivalent weight of Na2SO4?
The formula mass for sodium sulfate was calculated on page T-9. Referring to those numbers, the formula Na2SO4 means: two moles sodium (45.98 g), one mole sulfur (32.06 g), and four moles oxygen (64.00 g) combine to form one mole of sodium sulfate (142.04 g).
What is the equivalent weight of caco3?
The equivalent weight of calcium carbonate (CaCO3) is 50.045, as calculated above.
What is the equivalent weight of cuso4?
So, we have to know that the equivalent weight of copper sulfate is 80g.
What is the equivalent weight of h2o?
Explanation: Molecular weight of H 2 O is 18 grams. Its n-factor is 2. Its equivalent weight is 18/2= 9g.
What is the equivalent weight of nh4cl?
Ammonium chloride(NH4CI). there’s only one H + equivalent in the ammonium ion, so the equivalent mass is the same as the molar mass. If there were two H + equivalents, such as in H 2 SO 4 , then the equivalent mass would be half of the molar mass because half a molar mass would contain a mole of H + .
