When determining the sources of an error in solubility products there are several factors that need to be taken in to consideration. The density, PPM / parts per million and natural balance. Water and oil do not mix without being blended or forced to combine and that is only a temporary binding. That basic principal applies to all forms of error testing. Tests need to be conclusive and test all perimeters before presenting findings or coming to a conclusion.
If the object sinks, it's density can be found by knowing it's mass
and determining it's volume by immersing it in a liquid of known volume
and taking it's volume by difference with the displacement.
The only precaution I can think of in this procedure is to be sure
that there is no trapped air when the object is submerged. Well, another precaution I can think of is to be sure the object is dry when weighed.
There's only two things that go into a density calculation, mas and volume. So any measurement variable that affects either of those can give a false result. It's tough to limit it to three. More like infinite.
Someone could have their finger on the scale or the A/C could be on (blowing down on the scale). Temperature could slightly affect the capacity of a specific-size container.
angle at which incident radiation strikes surface, wavelength of radiation, thickness and optical complexity of the material.
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).
The element's average atomic mass.
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')
16 molar.
It is a known fact : Molar heat of sublimation = molar heat of fusion + molar heat of vaporization so, molar heat of vaporization = molar heat of sublimation - molar heat of fusion Mv = 62.3 kJ/mol - 15.3 kJ/mol Mv = 47 kJ/mol.

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

The molar extinction coefficient (also sometimes called molar absorbtivity coefficient) is a measure of how strongly a solution of a substance absorbs light (the value depends on the particular wavelength of light used). By passing light through a solution and determining how much of the light is absorbed, you can use the path length and molar extinction coefficient to determine the concentration of the solution.Look up "Beer-Lambert law" if you want details.
Molar conductivity at infinite dilution is when molar conductivity is limited. Molar conductivity is when electrolyte conductivity is divided by molar concentration.
Molar Mass of Carbon + Molar Mass of Silicon = Molar Mass of SiC. 12.0107 + 28.0855 = 40.0962 g / mol.
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.
16 molar.
The molar mass of glucose is 180,16 g.
It is a known fact : Molar heat of sublimation = molar heat of fusion + molar heat of vaporization so, molar heat of vaporization = molar heat of sublimation - molar heat of fusion Mv = 62.3 kJ/mol - 15.3 kJ/mol Mv = 47 kJ/mol.
to find molar mass you add the molar mass of the carbons 3(amu)+ molar mass of the hydrogens 8(amu) to find molar mass you add the molar mass of the carbons 3(amu)+ molar mass of the hydrogens 8(amu)
