Because size and weight can vary.
A hygroscopic substance absorbs moisture from the air. If an unknown being is being weighed before and after exposure to air, any increase in weight may suggest it is hygroscopic and has absorbed moisture from the air. Additional testing would be needed to confirm this hypothesis.
The unit of measurement most useful for a baseball's weight is ounces.
You can't, unless you know of which substance you have 2 litres (and the weight of said substance)
Yes, the properties of mass and weight can be useful in identifying different types of matter, though they are not definitive on their own. Mass is a measure of the amount of matter in an object, while weight is the force exerted by gravity on that mass. These properties can help differentiate materials based on density and can indicate purity or composition in some contexts. However, they should be used in conjunction with other properties, such as chemical composition and physical characteristics, for more accurate identification.
the molecular weight of a substance expressed in grams
Knowing the solubility of an unknown substance in water can help you calculate its molarity. It is however important to get its weight first.
To calculate weight using specific gravity, you multiply the specific gravity of the substance by the weight of the substance in air. This gives you the weight of the substance in a vacuum.
You can use properties like color, luster, hardness, cleavage, streak, and specific gravity to help identify an unknown mineral. Additionally, conducting tests such as acid reactions, magnetism, and fluorescence can also aid in identifying the mineral.
If the measured weight was too high, the calculated weight of the unknown would also be too high. If the measured weight was too low, the calculated weight of the unknown would also be too low. If there was no error in the measured weight, the calculated weight of the unknown would remain unchanged.
It is the French term for "net weight", which is the weight of a substance, not including the weight of the container it's in; "gross weight" includes the weight of the substance and the container.
Mass has to do with the amount of substance, along with the actual material property (like density).Suppose you have a sheet of paper and sheet of aluminum foil, which appear to be the same size (area). The aluminum is much denser than paper, but depending on the thickness you could have it where they both have the same mass. What you need is an identical volume of the substances, then compare the mass of those and from that calculate density, which is a property of the substance.I hope this example helps.

The substance with a molecular weight of 765.82 is the antibiotic called Azithromycin.
unknown
Unknown.
That quantity is known as the "weight" of the substance, and it depends on how much of the substance you have.
his weight is currently unknown to the public
