What else can I help you with?
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.
Does an increase in molecular weight speed up molecular movement?
no relation iz between molecular weight and movement which iz a function of temperature only.
What does normality mean in chemistry?
Normality is a way of expressing concentration, and is not used widely any more. It is the equivalent wt of a substance per liter of solution. The equivalent weight will depend on the reaction that take place, and can be the same as the molecular weight. Example: HCl has same equiv. wt. as mol. wt. because it has only 1 equivalent, i.e. one H. H2SO4 has TWO equivalents (2 H+) so, 1 molecular wt will be equal to 2 equivalent wts, and normality will be 2x the molarity.
How do you calculate molecular weight in electrophoresis?
To calculate the molecular weight of a protein in electrophoresis, you would use a standard curve generated with protein standards of known molecular weights run on the same gel. By plotting the migration distance of the standard proteins against their known molecular weights, you can then determine the molecular weight of your protein of interest based on its migration distance on the gel in comparison to the standard curve.
Why do different proteins have the same relative molecular mass?
Different proteins can have the same relative molecular mass because molecular weight alone does not determine a protein's structure or function. Proteins can vary in amino acid sequence, post-translational modifications, and three-dimensional structure while still having the same molecular mass. Thus, proteins with different compositions and functions can have similar molecular masses.
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.
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.
