What are the major sources of errors in determining the molar mass?

Answer 1

Sources of error are: isotopic compostion of elements, Atomic Mass of isotopes.

Answer 2

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.

Answer 3

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.

Answer 4

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.

Answer 5

angle at which incident radiation strikes surface, wavelength of radiation, thickness and optical complexity of the material.

Answer 6

Sources of error are: isotopic compostion of elements, Atomic Mass of isotopes.
