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.
Molecular weight of petrol?
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.
What is the molecular weight of chymotrypsin?
It has a molecular weight of 21,600 Daltons
If you have molecular weight how can you find equivalent weight?
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.
Which substance has a higher molecular weight a methylene blue or potassium permanganate?
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.

What is K value in PVC resin?
K Value is an indicator of molecular weight : K-57 is medium for injection molding,K-67 is medium-high for rigid extrusion, K-70 is higher for plasticized extrusion or calendering. K value relates to other ASTM indicators of molecular weight like Intrinsic Viscosity or Inherent Viscosity.

What is the average molecular weight of polytetrafluoroethylene or Teflon?
The average molecular weight of polytetrafluoroethylene (Teflon) is approximately 100,000 to 1,000,000 g/mol.
What is the average molecular weight of the compound in question?
The average molecular weight of the compound is the sum of the atomic weights of all the atoms in the molecule, divided by the number of atoms.
Number-average molecular weight of a polypropylene is 1000000 gmol Compute the number-average degree of polymerization?
Number-average degree of polymerization = (Number-average molecular weight of polymer) / (Molecular weight of repeating unit) For polypropylene, the molecular weight of the repeating unit is 42 g/mol. Thus, degree of polymerization = 1000000 g/mol / 42 g/mol = 23809.52.
