Answerer: 244.
Questioner: I don't know a lot about chemistry, I'm really asking this for a friend. But they said that the molecular weight of the dimer would be less than twice the weight of the acid. 244 seems to be almost exactly twice that weight. Is that the correct answer?
Answerer: Yea, as far as i think.
It has a molecular weight of 21,600 Daltons
To determine the equivalent weight from the molecular weight, you need to divide the molecular weight by the valence (or charge) of the compound. For example, for a compound with a molecular weight of 100 g/mol and a valence of 2, the equivalent weight would be 50 g/equiv.
Potassium permanganate has a higher molecular weight compared to methylene blue. The molecular weight of potassium permanganate is approximately 158.03 g/mol while the molecular weight of methylene blue is around 319.85 g/mol.
The formula for silver nitrate is AgNO3. Its molecular weight is 169.87g/mol.
The molecular weight of petrol can vary based on its composition, but it is typically around 114-120 grams per mole. This is a rough average as petrol is a mixture of hydrocarbons with different molecular weights.

Benzophenone can be converted into benzanilide by reacting it with aniline in the presence of a base, such as potassium hydroxide. The reaction proceeds via nucleophilic aromatic substitution, where the aniline replaces the oxygen in benzophenone, forming benzanilide. The product can be isolated and purified by techniques such as recrystallization.

To determine the equivalent weight from the molecular weight, you need to divide the molecular weight by the valence (or charge) of the compound. For example, for a compound with a molecular weight of 100 g/mol and a valence of 2, the equivalent weight would be 50 g/equiv.
To recrystallize benzanilide, you would first dissolve it in a hot solvent (such as ethanol) until it forms a clear solution. Next, slowly cool the solution to allow crystals to form. Filter the crystals, wash them with a cold solvent to remove impurities, and then allow them to dry to obtain pure benzanilide crystals.
Ethanol is often used in the recrystallization of benzanilide because it is a good solvent for benzanilide at high temperatures. When the mixture is cooled, benzanilide becomes less soluble in ethanol, leading to the formation of pure crystals as it precipitates out of the solution. Ethanol also helps to minimize impurities in the final crystal structure of benzanilide.
The molecular weight of vanillideneacetone is 192.214g/mol.
Sodium nitrate molecular weight is 84,9947.
Sodium nitrate molecular weight is 84,9947.
The molecular weight of insulin is approximately 5,800 Daltons.
The dipole moment of benzanilide is approximately zero because the molecule is symmetrical and the dipoles cancel each other out. Benzanilide consists of a benzene ring linked to an aniline group, resulting in opposing dipole moments that effectively cancel each other.
The weight average molecular weight of the compound is the average of the molecular weights of all the molecules in the sample, weighted by their relative abundance.
