What else can I help you with?
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 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.
Do giant molecules have charged ions?
Yes, polyurethane dispersions are usually anionic and have very large molecular weights.
Which molecular solid would have the lowest boiling point?
One with induced dipole attractions

What are the gram molecular weights of H2O?
18

If the yellow molecules have a molecular mass of 25 amu what is the molecular mass of the blue molecules?
Without additional information, it is impossible to determine the molecular mass of the blue molecules based solely on the molecular mass of the yellow molecules. Each type of molecule has its own unique molecular mass, and it cannot be inferred from other molecules.
What does amu unit stand for?
The amu unit stands for atomic mass unit, which is a standard unit of mass used to express atomic and molecular weights. It is defined as one twelfth of the mass of a carbon-12 atom, equating to approximately 1.66 × 10^-27 kilograms. The amu provides a convenient way to compare the masses of different atoms and molecules, reflecting their relative sizes and weights in chemistry and physics.
