The molecular weight of a liquid sample is determined by the mass of its molecules, typically expressed in grams per mole (g/mol). It can be calculated by adding the atomic weights of all the atoms in a molecule based on its chemical formula. To obtain the molecular weight of a liquid, one may also use techniques such as mass spectrometry or vapor pressure osmometry. The molecular weight is crucial for understanding the sample's properties, behavior in reactions, and interactions with other substances.

What is the molecular weight of cellulase?
it is depend on the purity of pectinase enzyme. to know exact value of mw you have to run SDS page for individual sample.
An unknown sample with a molecular mass of 180.0g is analyzed to yield 40 percent C 6.7 percent H and 53.3 percent O What is the empirical formula and the molecular formula of this compound?
The empirical formula is CH2O. To find the molecular formula, you need to calculate the empirical formula weight (30 g/mol) and divide the molecular mass (180.0 g/mol) by the empirical formula weight to get 6. This means the molecular formula is (CH2O)6, which simplifies to C6H12O6, the molecular formula of glucose.

What is the process to calculate the gram molecular weight of the unknown liquid?
To calculate the gram molecular weight of an unknown liquid, you need to determine the molecular formula of the liquid and then add up the atomic weights of all the atoms in the formula. This will give you the gram molecular weight of the unknown liquid.
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 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.
Which type of energy would exist in a liquid sample but not in a gas sample of the same molecular compound?
You think probable to intermolecular forces.
How many lb-moles of substance are present in the given sample?
To determine the number of lb-moles in a sample, divide the weight of the sample in pounds by the molecular weight of the substance. This will give you the number of lb-moles present in the sample.
Is molecular weight an intensive or extensive property?
Molecular weight is an extensive property because it depends on the amount of substance present. It increases proportionally with the quantity of molecules in the sample.
A sample of a volatile liquid is vaporized completely in a 240 cm3 flask at 135C and 1200 mm Hg The condensed vapor liquid weighs 0.837 grams What is the molecular weight The liquid contains 64?
The first step is to calculate the number of moles of the vapor. Use the ideal gas law to convert the given conditions to moles, which gives you 0.5 moles. Next, determine the molecular weight by dividing the mass by the number of moles, giving a molecular weight of 1.674 g/mol.
How will determine Molecular weight by Landsberger method?
we can determine the molecular weight from landsberger experiment for elevation of boiling point by using the formula M2=(KBW2)*1000/T'W1 where M2=molecular mass Kb=ebullioscopic constant or molal boiling point constant W2=mass of solute W1=mass of solvent T'=change in temprature
Why do you need a molecular weight ruler alongside your samples during electrophoresis?
A molecular weight ruler uses a sample of fragments of a known size (known as a molecular weight marker) to be placed alongside the experimental and control samples. It helps compare the migration distance of the experimental fragments to the migrating distance of the fragments of a known size that make up the molecular weight marker. Then the scientist can calculate an approx. size of their experimental samples.
How many molecules are contained in a 4.75-g sample of dimethylmercury?
To calculate the number of molecules in a sample, you need to know the molecular weight of the substance. The molecular weight of dimethylmercury is approximately 214.77 g/mol. Using this information, you can determine the number of moles in the 4.75-g sample and then convert that to the number of molecules using Avogadro's number.
What is the Molecular weight of diesel fuel?
233 g/mole estimated average molecular weight. Diesel fuel, like other petroleum products, is not one specific chemical compound but a complex mixture of organic compounds separated into ranges by their boiling point. For this reason, diesel doesn't have a specific molecular weight. However, you can talk about an "average molecular weight" of the mixture. EPA lists an estimated average molecular weight for diesel of 233 g/mole. http://www.epa.gov/athens/learn2model/part-two/onsite/es.htm The actual average molecular weight of diesel will vary from sample to sample depending on what grade of diesel it is (i.e. #1 diesel is light diesel), feedstock of the diesel, and the refining process of the diesel.
What is the molecular weight of cellulase?
it is depend on the purity of pectinase enzyme. to know exact value of mw you have to run SDS page for individual sample.
