True or false Gases with high molecular weights diffuse more slowly than gases with lower molecular weights?
True. Gases with high molecular weights have slower diffusion rates compared to gases with lower molecular weights due to their larger mass and lower average speed of the molecules.
How can one determine the molecular weight from a titration curve?
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.
What is the weight average molecular weight of the compound in question?
The weight average molecular weight of the compound is the average of the molecular weights of all the molecules in the sample, weighted by their relative abundance.
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.
What is the weight average molecular weight of the polymer in question?
The weight average molecular weight of the polymer is the average of the molecular weights of all the polymer chains in the sample, taking into account the weight of each chain.
What is the molecular weights of tubulin and dynein found in the flagella of chlamydomonas?
The molecular weight of tubulin is 54-55 kiloDaltons.
True or false Gases with high molecular weights diffuse more slowly than gases with lower molecular weights?
True. Gases with high molecular weights have slower diffusion rates compared to gases with lower molecular weights due to their larger mass and lower average speed of the molecules.
What are the gram molecular weights of H2O?
18

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.
How can one determine the molecular weight from a titration curve?
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.
Why can you separate the components of mixture?
They have different molecular weights and chemical/physical properties.
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.
How molecular weight and sedimentation constant is related to each other?
Molecular weight and sedimentation constant are related through the Svedberg equation, which states that the sedimentation constant (S) is inversely proportional to the molecular weight of a molecule. This means that larger molecules with higher molecular weights will have lower sedimentation constants, while smaller molecules with lower molecular weights will have higher sedimentation constants.
What is the weight average molecular weight of the compound in question?
The weight average molecular weight of the compound is the average of the molecular weights of all the molecules in the sample, weighted by their relative abundance.
