For example the two diatomic gases hydrogen and oxygen can combine to form a liquid water in an exothermic reaction as described by the following equation. A mole in chemistry is defined as the number or quantity of a chemical substance that consists of as many fundamental entities such as atoms molecules and ions.

Mole is a unit of concentration in SI. The mole is useful in chemistry because it is defined such that the mass of Avogadros number of particles atoms or molecules of a substance the molar mass is equal to the sum of the numerical values of the atomic masses of its constituent elements. For chemists the mole is used as a unit of measure with a concept similar to that of a dozen.

Also because we know that there are three atoms in each molecule of H 2 O we can also determine the number of atoms in the sample. 1 Although safety measures due to COVID-19 have limited or even canceled in-person lab work for many teachers. A mole mol is the amount of a substance that contains 602 10 23 representative particles of that substance.

It is used for calculating for the energy of substances. The mole is given by the number of atoms in exactly 12 g of 12C which turns out to be 602214. What is a Mole.

Virtual labs present a reasonable alternative. A mole in chemistry is a unit of measurement that tells us the quantity of a substance 6 x 1023 atoms make up one mole. What is the definition of a mole in chemistry.

Just like the dozen and the gross it is a name that stands for a number. The mole is a way to measure lots of atoms so a is definitely correct. Which statement BEST describes why we bartleby.

This concept helps chemists measure amounts of compounds and molecules in a more efficient way by grouping these units. A mole in chemistry is defined as the number or quantity of a chemical substance that consists of as many fundamental entities such as atoms molecules and ions. For example 2 moles is easier and more concise.

O c Moles are used because atoms and molecules are too small. 1 point A It can be used to find the number of molecules but not atoms or ions. What is the definition of a mole in chemistry.

The elementary entities that can be represented in moles can be atoms. Mole ratios are used as a means of comparison of substances in a balanced chemical equation in order to. The Mole - A Free Virtual Chemistry Lab Activity.

B It can be used to find the number of molecules or ions but not atoms. A mole is equal to the molecular mass of a compound. True An elements molar mass is equivalent to the atomic number of the element.

A mole in chemistry is defined as the number or quantity of a chemical substance that consists of as many fundamental entities such as atoms molecules and ions. O b Moles are used because a mole is the same as the atomic mass of an element. The mole is a measured used in chemistry formulas in areas such as stoichiometry as well as for balancing chemical.

A mole is defined so that one mole of carbon-12 atoms has a mass of exactly 12 grams. A mole is defined as 602214076 1023 of some chemical unit be it atoms molecules ions or others. O a Moles are used because they are units of mass.

The definition of a mole is an equality that can be used to construct a conversion factor. Which statement describes the quantities that can be found using the number of moles. Therefore the statement that best describes a mole is that it is used for directly comparing the amounts of substances.

Mole is a unit of concentration in SI. A dozen is universally known to equal 12 while a mole is universally known to equal 6021023. Therefore the statement that best describes a mole is that it is used for directly comparing the amounts of substances.

A mole in chemistry is a unit of measurement that tells us the quantity of a substance 6 x 1023 atoms make up one mole. Up to 256 cash back Which statement best describes a mole. The mole is a convenient unit to use because of the great number of atoms molecules or others in any substance.

The mole is the SI unit for amount of a substance. What is a mole used in chemistry as. 2 2 H.

It is used for directly comparing the amounts of substances. As described in a previous ChemEd X post I. Which statement BEST describes why we use moles when measuring quantities of atoms and molecules.

C It can be used to find the number of molecules atoms or ions. A mole is equal to the molecular mass of a compound. In the field of chemistry a mole is defined as the amount of a substance that contains exactly 602214076 10 23 elementary entities of the given substance.

1023 and is therefore a very large number so b is also correct. The number 60221407610 23 is popularly known as the Avogadro constant and is often denoted by the symbol N A. What is a mole used in chemistry as.

It is used for grouping chemical equations. Therefore the statement that best describes a mole is that it is.
