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.
What is the equivalent weight of anhydrous sodium acetate?
The formula for sodium acetate is CH3COONa and the equivalent weight is the same as the molecular weight (molar mass) which is 82.0343 g/mol.
What is the molar mass of a compound if its molecular weight is 58.44 dalton g/mol?
The molar mass of a compound is the same as its molecular weight, which is 58.44 g/mol.
Is molecular weight the same as molar mass?
Yes, molecular weight and molar mass are essentially the same concept in chemistry. They both refer to the mass of a molecule or compound, expressed in atomic mass units or grams per mole.
How will determine Molecular weight by Landsberger method?
we can determine the molecular weight from landsberger experiment for elevation of boiling point by using the formula M2=(KBW2)*1000/T'W1 where M2=molecular mass Kb=ebullioscopic constant or molal boiling point constant W2=mass of solute W1=mass of solvent T'=change in temprature
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.
Is the molecular weight the same as its atomic weight?
The molecular weight is the sum of the atomic weights of all the atoms contained in the molecule.
Is Molecular Weight the same as Data point?
No.
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
What is the equivalent weight of anhydrous sodium acetate?
The formula for sodium acetate is CH3COONa and the equivalent weight is the same as the molecular weight (molar mass) which is 82.0343 g/mol.
What is the molar mass of a compound if its molecular weight is 58.44 dalton g/mol?
The molar mass of a compound is the same as its molecular weight, which is 58.44 g/mol.
Is molecular weight the same as mass?
Technically... not really. It would perhaps be more accurate to use the terms formula mass and molecular mass rather than formula weight and molecular weight. This because in physical terms, weight is a force while mass is a measure of the amount of substance in something.
Will two molecules having the same molecular weight and charge have the same mobility in electrophoresis?
yes...!
How do you find out molecular wt using density?
I'm not exactly positive. But if you know the volume in grams and the mass (giving you density), then you should be able to figure out the molecular weight. The mass is the same as the molar mass, which I would assume is the same as the molecular weight, but I'm not positive.
How many mmol equal 52 meq of potassium?
Since potassium has a valence of one, its equivalent weight is the same as its molecular weight; therefore, 2.9.
How do you calculate number average molecular weight given molecular weight range and fraction?
To calculate the number average molecular weight, multiply each molecular weight value within the range by its corresponding fraction, then sum up these products. This sum represents the numerator of the equation. Next, sum up all the fractions in the denominator. Finally, divide the numerator by the denominator to obtain the number average molecular weight.
