## What is mole concept in chemistry class 11?

A mole is defined as that amount of substance which contains Avogadro’s number of atoms if the substance is atomic or Avogadro’s number of molecules if the substance is molecular. … 1 mole of carbon atoms = 6.022 ×1023 atoms of carbon.

## What is stoichiometric mole?

A common type of stoichiometric relationship is the mole ratio, which relates the amounts in moles of any two substances in a chemical reaction. We can write a mole ratio for a pair of substances by looking at the coefficients in front of each species in the balanced chemical equation.

## What is mole concept example?

Moles can be used to represent a chemical reaction on a macroscopic level. For example, if a mole of water undergoes decomposition, it releases 0.5 moles of oxygen and a mole of hydrogen gas. The concept of a mole is used in determining the molarity of a substance.

## What are the concepts of stoichiometry?

Stoichiometry is the study of measuring or predicting the amount of reactants or products in a chemical reaction based on the variables such as the mass of reactants or products, the limiting reactant and the balanced chemical equation.

## How many atoms are in a mole?

The value of the mole is equal to the number of atoms in exactly 12 grams of pure carbon-12. 12.00 g C-12 = 1 mol C-12 atoms = 6.022 × 1023 atoms • The number of particles in 1 mole is called Avogadro’s Number (6.0221421 x 1023).

## What is stoichiometry Class 11?

Stoichiometry is defined as the exact numbers which indicate the actual proportions of the reactant and product. … Stoichiometry is important for writing balanced chemical reactions. Thus the ratio of all the reactants and products can be determined. Stoichiometry is based on the law of conservation of mass.

## What is mole 10th?

The mole is the unit of measurement in the International System of Units (SI) for an amount of substance. … 1 mole of hydrogen atoms represents 6.022 × 1023 hydrogen atoms. 1 mole of hydrogen molecules represents 6.022 × 1023 hydrogen molecules. 1 mole of water molecules represents 6.022 × 1023 water molecules.

## What is mole concept and molar mass?

Related to the concept of moles, the molar mass of a substance refers to the total mass of one mole of a substance (i.e. molar mass = mass of one mole which is equal to 6.02214076×1023 number of particles of that substance ). … So numerically, one molar mass = mass of (6.02214076×1023 * Atomic mass of that element).
