Which best describes the mole concept?
Each names a given number of objects. Which statement best describes a mole? It contains 6.02 x 10^23 particles of a given substance.
Which statement best describes a mole it is used mainly for writing?
Therefore, the statement that best describes a mole is c. It is used for directly comparing the amounts of substances.
Which values gives the number of particles in 1 mol of a substance?
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.
How was the mole determined?
The mole was defined by International Bureau of Weights and Measures as “the amount of substance of a system which contains as many elementary entities as there are atoms in 0.012 kilogram of carbon-12.” Thus, by that definition, one mole of pure 12C had a mass of exactly 12 g.
How would you describe a mole?
A mole is defined as 6.02214076 × 1023 of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
Which of the below statements best describes the purpose for using moles in chemistry?
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.
Which simple definition best describes the meaning of the word mole as used in chemistry?
The mole is an amount unit similar to familiar units like pair, dozen, gross, etc. It provides a specific measure of the number of atoms or molecules in a bulk sample of matter. A mole is defined as the amount of substance containing the same number of discrete entities (atoms, molecules, ions, etc.)
Which of the following best describes the meaning of molar mass?
Molar mass is defined as the mass in grams of one mole of a substance. The units of molar mass are grams per mole, abbreviated as g/mol.
What can be said about 1 mol Ag and 1 mol AU?
Avogadro’s number. What can be said about 1 mol Ag and 1 mol Au? … They contain the same number of atoms.
How do you calculate moles from ions?
Number of mol is calculated by ratio of given mass to the molar mass. After calculating the number of moles, the number of ions will be equal to the product of the number of moles and Avogadro’s number.
How do you calculate the number of moles using Avogadro’s?
Avogadro’s number is a very important relationship to remember: 1 mole = 6.022×1023 6.022 × 10 23 atoms, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro’s number. To convert from atoms to moles, divide the atom amount by Avogadro’s number (or multiply by its reciprocal).
