The molecular weight of free glucose is 180.2 while that of glucose in glycogen is 160 explain this anomaly with structural diagrams?
Put the following glucose solutions in order of least concentrated (A) to most concentrated (E) (note: mw of glucose is 180)10 grams glucose in 75 millilitres of water600 mM glucose5 mg in 1 mL water7.5 mM glucose in 10 mM NaCl10 % (w/v) glucose
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.
What is the relationship between molecular weight and density in a substance?
The relationship between molecular weight and density in a substance is that generally, substances with higher molecular weights tend to have higher densities. This is because heavier molecules are more tightly packed together, leading to a higher mass per unit volume, which results in a higher density.
Compute the degree of polymerization of polystyrene?
The degree of polymerization(n) is the ratio between Molecular weight(M) and the molar mass of the repeating unit in a polymer(m). M=n*m The molar mass(m) of the monomer (styrene) is 104.15 grams/mol if you are given a Molecular weight, just devide by m, and you've got it!
What is equivalent weight of zinc sulphate he-pta hydrate?
The equivalent weight of zinc sulfate hepta-hydrate is the molecular weight divided by the number of positive or negative charges contributed by its formula unit in a reaction. For zinc sulfate hepta-hydrate, the molecular weight is 287.56 g/mol and it has a divalent zinc atom which contributes two positive charges, so the equivalent weight would be 287.56/2 = 143.78 g/mol.
What is the molecular weight of a compound in daltons and how does it convert to grams per mole (g/mol)?
The molecular weight of a compound is measured in daltons, which is a unit of mass used for atoms and molecules. To convert daltons to grams per mole (g/mol), you can use the conversion factor 1 dalton 1 g/mol. This means that the molecular weight in daltons is equal to the molecular weight in grams per mole.

What is the difference between the Dalton and gram per mole (g/mol) units in measuring the molecular weight of a substance?
The Dalton unit is used to measure the mass of individual atoms or molecules, while the gram per mole (g/mol) unit is used to measure the average mass of a mole of atoms or molecules.
What is molar quantity?
Molecular weight (unit) of salt dissolved in liter (unit) volume of water.
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.
What molecule is larger glucose or sodium chloride?
Wate is molecular , H2O. NaCl is giant ionic laattice and is not molecular when normally encountered. In terms of mass the formula unit of NaCl is greater than than the molecular mass of water.
What is the unit of molecular wt?
The unit for molecular weight is typically in atomic mass units (u) or daltons (Da). It represents the sum of the atomic weights of all the atoms in a molecule.
Is Dalton the same as g/mol?
No, Dalton is a unit of atomic mass, while g/mol is a unit of molar mass.
What is the molecular formula of a compound if the weight is of a unit of the compound is 120 and the empirical formula is C3H4?
To find the molecular formula, you first need to calculate the empirical formula mass of C3H4. C3H4 has an empirical formula weight of 40 g/mol. If the molecular weight is 120 g/mol, then the molecular formula would be 3 times the empirical formula, so the molecular formula would be C9H12.
What is the small unit of mass used to label the weight of atoms?
The unified atomic mass unit (symbol: u) or dalton (symbol: Da)
How do you compare Dalton and micrometers?
Dalton is a unit of mass used to express atomic and molecular mass, while micrometers are units of length used to measure very small distances, typically in the range of micrometers (µm). They are different units used in different contexts - Dalton in chemistry for atomic mass and micrometers in engineering and microscopy for length measurements.
What is the basic unit of cellulose?
basic unit of cellulose is glucose
