What is the SI base unit used to measure the amount of substance?
The base unit for the amount of a substance is an hour.
What is a name for a mole?
Another name for a mole is the gram-molecule. It is a measurement used to express amounts of a chemical substance.
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.
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 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.
The amount of gas referred to in moles is called?
So you're asking.. Is the volume of gas moles? In a simple answer, no it is not. Moles is yes, a unit of measurement. A mole is a unit of measurement used in chemistry to express the amounts of molecules within a substance. 1 mole is equal to = 6.0022x10^23. For example, to get one mole of CARBON You need to get 12g. (atomic mass) But some things can be interpreted as mol/L (this is the molarity of a substance)
What does a mole measure?
An instrument can not be used to measure moles because moles is the amount of grams of a substance divided by the molar mass of the substance. This can not be measured and has to be calculated.
What is the SI unit used to measure the number of representative particles in a substance?
its the mole.
What is one mole of elements and compounds?
One mole is a quantity used to describe a group containing its 6.022 x 1023 particles.For example :-Substance quantity mass(g)carbon one mole 6oxygen one mole 16nitrogen one mole 14Hydrogen one mole 1silver one mole 108sodium chloride one mole 58.5
What is a mole used in chemistry as?
Mole is a unit of concentration in SI; a mole is equal to the molecular mass of a compound.
What is used to measure the number of representative particles in the substance?
mole
What unit is used to measure the mass of an atom?
mole
