Why is mole concept important?
Explanation: THE mole is important because it allows chemist to work with a subatomic world with macro world units and amount. Atoms molecules and formula units are very small and very difficult to work with usually. However the mole allows a chemist to work with amount large enough to use.
What is a mole how is the mole concept useful in chemical calculations?
Mole = Mass/ Molar mass. The molar mass can be easily identified just by adding the atomic masses. Therefore, by using the mole concept, we can convert the available amount into moles. That will be useful to determine the stoichiometry of reacting compounds or molecules.
What is a mole and why is it important in chemistry?
A mole is a very important unit of measurement that chemists use. A mole of something means you have 602,214,076,000,000,000,000,000 of that thing, like how having a dozen eggs means you have twelve eggs. Chemists have to measure using moles for very small things like atoms, molecules, or other particles.
What is a mole What is it used for and why?
mole, also spelled mol, in chemistry, a standard scientific unit for measuring large quantities of very small entities such as atoms, molecules, or other specified particles. The mole designates an extremely large number of units, 6.02214076 × 1023.
Why is it useful to use moles to measure chemical quantities quizlet?
Chemists use the mole because it is a convenient way of knowing how many representative particles are in a sample. … Each one-mole quantity has 6.02 1023 particles (atoms), but they will have different masses. State the conversion factors needed to convert between mass and moles of the element fluorine.
Which statement best explains the purpose of using a mole in the measurement of matter?
Which statement best explains the purpose of using a mole in the measurement of matter? It allows chemists to deal with a large number of atoms.
What is a mole in chemistry quizlet?
The mole is the amount of substance that contains as many particles (molecules, ions or atoms) as there are in 12g of carbon. This number has been found to be 6.02 x 10^23. Molar Mass (M) Numerically equal to the relative molecular mass of each element in a molecule.
What is the mole in chemistry?
The mole is the amount of substance of a system which contains as many elementary entities as there are atoms in 0.012 kilogram of carbon 12; its symbol is “mol”. … Notice that the definition of the mole is an amount of substance. We will often refer to the number of moles of substance as the amount of the substance.
