What are the major sources of error in your determination of the molar mass -?

Without more details this is a shot in the dark but I assume that you have the moles and weight of the compound. You then calculated the molar mass from these numbers.
The sources of error with doing this experimentially is that you may have lost some of the sample in transferring, you may have weighed the sample incorrectly, and you could have made mistakes in calculations (all human errors).

What is the precaution steps in the experiment of the determination of the molar mass of a volatile liquid?
make sure the flask is cooled about 15 minutes before weighing the flask to avoid the mass error
What effect Dimers molar mass determination volatile liquids?
I'm trying to figure out how it affects molar mass as well. However, I do know that it decreases the pressure which is in the denominator of the equation to find the molar mass once the ideal gas equation is manipulated. So i think that with the formation of dimers the molar mass would increase?
What is the molar mass of KC2H3O2?
Molar mass of KC2H3O2 = 98.14232 g/mol Molecular weight calculation: 39.0983 + 12.0107*2 + 1.00794*3 + 15.9994*2 See the 'sources and related links' at bottom of this answer. The site there works the molar mass out for you automatically, all you have to do is insert 'KC2H302')
What is the molecular formula of the compound CH2 with molar mass equals 168?
1. CH2 is the chemical formula of the radical methylene. The structure is H-C-H. 2. The molar mass of CH2 is approx. 14; 168 is an error.
What is the molar mass Na?
The expression"molar mass" for sodium is not corresct. After today rules of IUPAc correct is atomic weight. The atomic weight of sodium is determined very exact: 22,989 769 28 (2013 data); the error is +/- 2 for the last digit of this value.
What are the major sources of error in your determination of the molar mass?
1.) Some of the sample may have been lost in between testing that could resulted in slight error when calculating your molar mass. 2.) Weighing sample incorrectly and having too low/high std. deviation

How do you determine the number of atoms for each element in a chemical formula?
A chemical analysis and a molar mass determination are needed.

What is the difference between partial molal quantities and partial molar quantities?
During the determination of the partial molal quantities the weight of the solution to which a substance is added is taken into consideration while in case of the partial molar quantity the volume is taken into consideration.
What is the molar mass of KC2H3O2?
Molar mass of KC2H3O2 = 98.14232 g/mol Molecular weight calculation: 39.0983 + 12.0107*2 + 1.00794*3 + 15.9994*2 See the 'sources and related links' at bottom of this answer. The site there works the molar mass out for you automatically, all you have to do is insert 'KC2H302')

What is molar conductivity at infinite dilution?
Molar conductivity at infinite dilution is when molar conductivity is limited. Molar conductivity is when electrolyte conductivity is divided by molar concentration.
What is the molar mass of SiC?
Molar Mass of Carbon + Molar Mass of Silicon = Molar Mass of SiC. 12.0107 + 28.0855 = 40.0962 g / mol.
If you know the molar masses of the reactants in a chemical reaction can you determine the molar masses of the products?
If you know know the molar masses of the reactants in a chemical reaction you can determine the molar masses of the products because the combined molar masses of the reactants equals the combined molar masses of the products.
What is the molar concentration of nitric acid?
16 molar.
