What is the importance of mole concept in chemistry?

What is the importance of the mole concept?

The mole is important because it allows chemists to work with the subatomic world with macro world units and amounts. Atoms, molecules and formula units are very small and very difficult to work with usually. However, the mole allows a chemist to work with amounts large enough to use.

What is the importance of the mole concept in chemistry select all that apply?

What is the importance of the mole concept in chemistry? Select all that apply. It allows chemists to study and measure substances within the subatomic world. It allows chemists to change grams to the number of particles through the mole, even though particles cannot be seen.

What is the importance of the mole concept in chemistry quizlet?

The mole concept is important in chemistry because it relates grams of a substance to the number of atoms or molecules being weighed. For instance, we know that if we weigh 63.55 g of pure copper, then we have about one mole (6.022 x 1023) of copper atoms.

What is a mole how is the mole concept useful in chemical calculations quizlet?

a Mole is the SI unit of measurement used to measure the number of things, usually atoms or molecules. … The concept of mole is very important in chemistry, almost all the calculations, at least in general chemistry, involve the mole. You just studied 10 terms!

What is the importance of the molar mass of any compound What does the molar mass represent?

The molar mass of a compound can be calculated by adding the standard atomic masses (in g/mol) of the constituent atoms. Molar mass serves as a bridge between the mass of a material and the number of moles since it is not possible to measure the number of moles directly.

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.

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.

Why might it be important to know the number of moles in a sample instead of only the mass of the sample?

For example, if we know the mass and chemical composition of a substance, we can determine the number of moles and calculate number of atoms or molecules in the sample. Likewise, if we know the number of moles of a substance, we can derive the number of atoms or molecules and calculate the substance’s mass.

How is mole ratio used in a chemical reactions?

The mole ratio compares the number of moles in a balanced equation. This is the comparison between the coefficients in front of the chemical formulas. Mole ratios are used to predict how much product a reaction forms or to determine how much reactant is needed to make a set amount of product. …
