How do you find the equivalent weight of N2?
The equivalent weight of an element is its gram atomic weight divided by its valence. When Nitrogen (N2) is converted into Ammonia (NH3) ( N H 3 ) , then the equivalent weight of Nitrogen (N2) will be 4.67.
How do you find the equivalent weight of a molecule?
Equivalent Weight = Molecular weight/ Valency Also, read: Chemical Reaction.
What is the equivalent weight of o2 molecule?
So, for 1 mole of oxygen molecule the number of moles of electrons involved is 4 which is also the n-factor. The molecular mass of oxygen is 32. Therefore, the equivalent weight of ${{O}_{2}}$ in the reaction is 8 g.
How do you find the equivalent of a molecule?
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 the equivalent weight of no2?
answer is 822=822 .
How do you find the equivalent weight of NH3?
- N2⟶NH3.
- Oxidation no. of N in N2=0.
- Oxidation no. of N in NH3=−3.
- Molecular weight of NH3=17g.
What is the equivalent weight of h3po2?
1 grams
(D) 49.5. Hint: As we know that in a chemical reaction the equivalence of a substance is explained as the amount of which combines with 1 mole of the hydrogen atoms or replaces the same number of hydrogen atoms in the reaction. Thus equivalent weight in grams is the weight of 1 grams.
What is the N factor of n2?
This means that 1 atom of N shares 3 electrons with H atoms and so 2 N atoms will share in total 6 electrons. So, the n-factor of ${N_2}$ is 6. Molecular weight of ${N_2}$ is ${x_2}$ and equivalent weight is ${y_2}$ (given in the question).
How do you calculate gram equivalent weight?
Gram equivalent weight is equal to mass in grams numerically equal to Equivalent Weight. To calculate the Gram Equivalent Weight, we use the formula Eq = MW / n.
What is the equivalent weight of nh3?
17g/
Ammonia exchanges 1 electron, being monoacidic in nature. Hence, the equivalent mass of ammonia is 17g/eq or 17kg/mol.
How do you calculate the molecular weight of N2 or O2?
When a substance like N2 or O2 is given, its molecular weight can be calculated from the values (given in standard tables) of relative atomic weights of the component atoms contained in the molecule. Good question. But the question is incomplete! That it is an incomplete question is not appreciated by many.
What is the difference between molecular weight and equivalent weight?
When a substance like N2 or O2 is given, its molecular weight can be calculated from the values (given in standard tables) of relative atomic weights of the component atoms contained in the molecule. However, equivalent weight of a substance cannot be calculated just from knowing the substance (its chemical formula)!
What is the equivalent weight of N2 in grams?
change in oxidation number of N in N 2 in formation of NH 3 =3 For 2 N atom = 6 So equivalent weight of N 2 =28/6=14/3 g (molecular weight of N 2 =28 g) Equivalent weight of NH 3 = 17/3 g (molecular weight of NH 3 =17 g)
What is the equivalent weight of H2O2 in this reaction?
Since the reaction also involves 2 mol of H2O2, the number of electrons transferred per mole of H2O2 is n = 2 mol e- 2 mol H2O2 = 1lmol electrons per mole of H2O2 ∴ Equivalent weight = MM n = 34.01 g 1 = 34.01 g The equivalent weight of H2O2 in this reaction is 34.01 g.
