Why can mass or weight not be used to identifiy a substance?
ClurieBrileygp1102
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.

What is the formula of equivalent weight?
Equivalent weight = Molar mass of a substance/electrical charge of the ions (positive or negative) formed in solution Also the equivalent weight of a substance react with 1 mole of hydrogen. Today this expression is rarely used.
Which term is used to represent the mass of 1 mole of molecules of a substance?
This is equal to the molar mass of this substance.
Is the mass no same as atomic weight?
No, because a mass is the amount of matter and object has, while the weight is caused by gravity pushing down onto the object.The weight of an object is usually about 10 times the mass.The term atomic weight is used for chemical elements (after the rules of IUPAC).The term isotopic mass is used only for a specific isotope.
A laboratory equipment used for measuring the weight.?
A balance is used for measuring mass. A scale is used for measuring weight. (Usually a scale us used for mass.)
How is stoichiometry used to calculate the mass of a substance?
Unit conversion factors are used to convert between units of grams and moles.

How much does 180 liters weigh?
A liter is a unit of volume whereas any weight is a unit of mass. To determine how much a volume of any substance weighs, the density of the substance at the current temperature needs to be found. Typically, density is expressed in g/mL. Once the density has been determined, the equation density=mass(grams)/volume(liters) is used to determine the mass or weight of the substance.
Define one mole of a substance applied to atomic structure?
A mole is used to measure the amount of substance.1 mole of any substance contains 6.023 x 1023 molecules of that substance. 1 mole of a substance has mass equal to the atomic weight or molecular weight expressed in grams. Note:The number "6.023 x 1023" is called Avogadro's Number
Why do scientist measure mass and volume?
So they can determine the density of a substance. Density = mass/volume. Density can be used to identify a substance.
Why is the average mass used when calculating grams of a substance?
the elements in the substance are mixtures of their isotopes
What is the formula used to calculate the weight of an object if you were given the mass in kilograms?
weight=mass*gravity
How could density be used to determine the mass of a particular volume of a substance?
In a set volume of any substance increasing the density increases its mass
What is the definition for triple balance beam?
The triple beam balance is a tool used to distinguish the weight of an objectÕs mass through grams. Triple beam balance is commonly used in school and laboratories.
How could density be used to determine the mass of particular volume of a substance?
In a set volume of any substance increasing the density increases its mass
What is the use of weight-hanger in physics laboratory?
Weight-hangers are used to add desired amounts of weight to create the mass needed. The mass created is used for experiments involving mass, acceleration and force.
Why is the average atomic mass used when calculating grams of a substance?
the elements in the substance are mixtures of their isotopes
