What is KOH equivalent weight?
The equivalent weight of KOH (potassium hydroxide) is the molecular weight divided by the number of equivalents of the species. For KOH, since it donates one hydroxide ion (OH-), its equivalent weight is equal to its molecular weight (39.10 g/mol for K + 16.00 g/mol for O + 1.01 g/mol for H) divided by 1, giving an equivalent weight of 56.11 g/mol.
How can calculate equivalent weight of calcium carbonate?
The equivalent weight of calcium carbonate can be calculated by dividing its molecular weight by the number of acidic hydrogen ions that it can donate in a reaction. In the case of calcium carbonate, it can donate two moles of hydrogen ions, so the equivalent weight would be its molecular weight divided by 2.
Equivalent weight of sodium thiosulphate is equal to its molecular weight why?
The equivalent weight is the gram molecular weight divided by the number of electrons lost or gained by each molecule; e.g., potassium permanganate (KMnO4) in acid solution, 158.038/5 g; potassium dichromate (K2Cr2O7), 294.192/6 g; and sodium thiosulfate (Na2S2O3·5H2O), 248.1828/1 g. In case of Sodium Thiosulfate the reation proceeds as under: I2 + 2 Na2S2O3 → Na2S4O6 + 2 NaI 2 Na2S2O3 ≡ I2 ≡ Cl2 ≡ 2 e Hence Na2S2O3 ≡ 1 e Thus Molecular weight devded by 1 is the equivalent weight & hence both have same value
Chlorine diffuses 2.04 faster than gas Q Find molecular weight of gas Q?
To find the molecular weight of gas Q, we can use Graham's law of diffusion. The rate of diffusion is inversely proportional to the square root of the molecular weight. Since chlorine diffuses 2.04 times faster than gas Q, we set up the equation (rate of Q)/(rate of Cl2) = sqrt(Molecular weight of Cl2 / Molecular weight of Q), then solve for the molecular weight of gas Q.
What is the molecular weight of chymotrypsin?
It has a molecular weight of 21,600 Daltons
What is equivalent weight of a reducing agent?
Molecular weight/basicity
Is gram equivalent weight equal to molecular weight divided by two?
No, gram equivalent weight is molecular weight divided by n, where n is the number of equivalents of the substance involved in the reaction. It is not always equal to molecular weight divided by 2.
Equivalent weight of succinic acid?
The equivalent weight of succinic acid is the molecular weight divided by the number of acidic hydrogen atoms. Since succinic acid has two acidic hydrogen atoms, its equivalent weight is molecular weight/2. The molecular weight of succinic acid is 118 g/mol, so its equivalent weight is 118/2 = 59 g/mol.
How do you calculate equivalent weight of oxide?
To calculate the equivalent weight of an oxide, you first determine its molecular weight. Then you look at how many oxygen atoms are present in the formula of the oxide and divide the molecular weight by that number of oxygen atoms. This result is the equivalent weight of the oxide.
What is equivalent weight of benzene?
The molecular weight of benzene is 78. Its equivalent weight is the molecular weight divided by the functionality. It depends on the reaction what the functionality is. Assuming it is reacting with chlorine and UV light, the functionality is 6 so the equivalent weight would be 78/6 = 13. If it was involved in a reaction involving the double bonds, there are 3 of them and the equivalent weight would be 78/3 = 26.
Equivalent weight of NaHPO4?
The equivalent weight of NaHPO4 is determined by calculating the molecular weight divided by the change in oxidation state per reacting equivalent. For NaHPO4, the molecular weight is 137.99 g/mol, and it can donate 1 equivalent of H+ or accept 1 equivalent of OH-. Therefore, the equivalent weight of NaHPO4 is 137.99 g/mol.
Is the molecular weight and equivalent weight of aniline is same?
No, the molecular weight and equivalent weight of aniline are not the same. The molecular weight of aniline (C6H5NH2) is around 93.13 g/mol, while the equivalent weight is calculated based on the number of replaceable hydrogen atoms in the molecule, which for aniline is 46.57 g/equiv.
When is the molecular weight of an acid the same as its equivalent weight?
The molecular weight of an acid is equal to its equivalent weight if the acid donates only one proton (H+ ion) per molecule. This is because the equivalent weight of an acid is the molecular weight divided by the number of protons it donates.
Which of the following has same equivalent and molecular weight?
If two substances have the same equivalent weight, it means the number of equivalents per mole is the same for both substances. Therefore, the molecular weight of these substances would also be the same, as equivalent weight is derived from the molecular weight and valence of the substance.
What is the equivalent weight of H2O?
Molecular weight of H2O is 18 grams. Its n-factor is 2. Hence, its equivalent weight is 18/2= 9g
What is the equivalent weight of ammonium thiocyanate?
The equivalent weight of ammonium thiocyanate is calculated by dividing the molecular weight by the total positive or negative charge of the compound. For ammonium thiocyanate (NH4SCN), the molecular weight is approximately 76.12 g/mol and the total positive charge is +1 (from the ammonium ion), so the equivalent weight is 76.12 g/mol.
What is the equivalent weight of zirconium sulphate?
The equivalent weight of zirconium sulfate is calculated by dividing the molecular weight by its valency. Zirconium sulfate has a molecular formula of Zr(SO4)2, so its valency would be 2. The molecular weight of zirconium sulfate is around 332 g/mol, so the equivalent weight would be around 166 g/mol.
