How do you apply mole concept in real life?
In chemistry, the mole is a unit used to talk about atoms. It is similar to other units we use everyday. For example, you might walk into the local doughnut shop and order a dozen doughnuts. In doing so, you know that you will get 12 of these snacks and the clerk knows to give you 12.
Where and how do we use mole and Avogadro’s number?
One mole of a substance is equal to 6.022 × 10²³ units of that substance (such as atoms, molecules, or ions). The number 6.022 × 10²³ is known as Avogadro’s number or Avogadro’s constant. The concept of the mole can be used to convert between mass and number of particles.. Created by Sal Khan.
How will you relate the concept of mole to Avogadros number?
The mole allows scientists to calculate the number of elementary entities (usually atoms or molecules) in a certain mass of a given substance. Avogadro’s number is an absolute number: there are 6.022×1023 elementary entities in 1 mole. This can also be written as 6.022×1023 mol-1.
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.
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 the application of Avogadro’s law?
Some of the applications of Avogadro’s law are: (i) It explains Gay Lussac’s law of combining volumes. (ii) It determines atomicity of gases. (iii) It helps to determine the molecular formula of a gas. (iv) It helps to establish relationship between molecular mass and vapour density.
What is mole concept used for?
The mole can be used to determine the simplest formula of a compound and to calculate the quantities involved in chemical reactions. When dealing with reactions that take place in solutions, the related concept of molarity is useful.
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.
