Why you do find it useful to have two units for the amount of substance the kilogram and the mole?

Kilogram and mole really measure to very different things. Kilogram is used to measure the mass; the mole is closely related to the number of particles. 1 mole of a substance always has (number of Avogadro) particles. Therefore, you can't say in general that a kilogram is so-and-so many moles; this depends on the substance. For example, a mole of hydrogen atoms has a mass of 1 gram, while a mole of oxygen atoms has a mass of 16 grams.

∙ 11y agokilogram is useful to use kilogram as unit whenever we want to consider a specific amount of mass without considering the number of microscopic atoms or molecules present in it

Why do we find it useful to have two units of the amount of substance the kilogram and mole?
When we are concerned with the number of particles than we use Mole as the unit of amount of substance because one mole of a substance contains the equal number of particles (i.e., 6.022×10^-23)Butin case when we are concerned quantity of matter we use the unit Kilogram.
What is one fundamental units of the metric system?
The metric, or SI, system has seven base units from which all other units are derived. They are; metre, distance. second, time. kilogram, mass. ampere, electrical current. kelvin, temperature. candela, luminous intensity. mole, amount of substance.
Basic unit of the metric system?
There are seven base units from which all other units are derived. length; metre temperature; kelvin time; second mass; kilogram electrical current; ampere amount of substance; mole luminous intensity; candela
How much mass is a kilogram?
That completely depends on two things -- whatliquid substance you have, and how much of it you have. For example, if it's pure water and you have one liter of it, then its mass is very close to 1 kilogram. If you have only one-half liter of it, then its mass is one-half kilogram, but if you replace the water with mercury, then its mass is 6.8 kilograms. So you see, it depends on the substance, and the amount of it.
What is the base unit of measure for the metric system?
the international system of units or SI units have 7 base units for the measurement of different types of quantities. it uses the following units: meter - length kilogram - mass second - time kelvin - temperature ampere - current candela - luminous intensity mole - amount of substance
Why do you found it useful to have two units for the amount of substance the kilograms and the mole?
Actually, the kilogram and the mole measure two quite different things. The kilogram is a unit of mass. The mole is a unit of amount of substance, in the sense of the amount of atoms or molecules (in multiples of Avogadro's number). The same amount of kilograms can have varying amounts of moles, for different substances.

Newtons are units to use when measuring?
One newton (N) is equal to the amount of force needed to move 1 kilogram of substance one centimeter per second. This unit of measure can be useful when measuring the amount of force medium to large sized objects experience.

What units is parts of the international system of units?
In the SI system, the basic units are kilogram (mass) meter (distance) second (time) ampere (electric current) kelvin temperature) mole (amount of chemical substance) candela (luminous intensity).
What are all SI units expressed of?
The basic units of the SI system are• metre : length• kilogram : mass• second : time• ampere : electric current• kelvin : thermodynamic temperature• mole : amount of substance• candela : luminous intensity.Other units are derived from these.

What are the metric untists?
Assuming that you mean "units", the basic units are • metre : length• kilogram : mass• second : time• ampere : electric current• kelvin : thermodynamic temperature• mole : amount of substance• candela : luminous intensity.And then, there are hundreds of derived units for measuring other attributes.
How is cubic units useful?
They allow you to describe the volume of a substance or the capacity of a container.

What is the unit to measure the amount of matter in an object?
The amount of substance is expressed in moles. One mole corresponds to 6.022 * 1023 atoms or molecules. It is one of the base units in the International System of Units, and has the unit symbol mol."Amount of matter" is a very informal description of a property formally known as mass. The SI unit for mass is the kilogram.
