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.

The equivalent weight of potassium permanganate in alkaline medium is 31.6 g/mol. This value takes into account the reduction of permanganate ions to manganese dioxide in alkaline conditions, resulting in a different equivalent weight compared to acidic conditions.
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.
KMnO4 is the formula; The molecular weight is 158. The substance is a deep purple/almost black solid which in water turns intense purple.
Equivalent weight of KMnO4 is equal with molar weight of KMnO4. The some is and for K2MnO4, K2MnO4 - e +OH- --------- KMnO4 + KOH In general, Equivalent weight = Molar weight / Number of electrons that take or give one molecule Equivalent weight of KMnO4 = Molar weight of KMnO4 / 1
Potassium permanganate diffuses faster than methylene blue because it has a smaller molecular size and lower molecular weight, allowing it to move more quickly through the medium. Additionally, potassium permanganate has a more polar nature compared to methylene blue, which can also influence its diffusion rate in certain environments.
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
% by mole. There are six elements in KMnO4 only one is K so 1/6 which is 16.67% % by mass. Molar weight of K 39grams/mole. Molar weight of KMNO4 154 grams/mole so 39/154 =25%
the equivalent weight of chlorine is 35.453, which is also it's atomic weight.
Methylene Blue has a higher molecular weight than the compound potassium permanganate. Potassium permanganate has smaller, lighter molecules which diffuse faster than methylene blue's larger, heavier molecules.
To determine the molecular weight from a titration curve, one can identify the equivalence point on the curve where the amount of titrant added is equal to the amount of analyte present. By knowing the molarity of the titrant and the volume added at the equivalence point, one can calculate the moles of analyte. Then, by dividing the mass of the analyte by the moles, the molecular weight can be determined.
The equivalent weight of hydrogen peroxide is 17 g/mol.
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.
