What is the unit of 1 mole?

The mole, symbol mol, is the SI unit of amount of substance. One mole contains exactly 6.022 140 76 x 1023 elementary entities. This number is the fixed numerical value of the Avogadro constant, NA, when expressed in the unit mol1 and is called the Avogadro number.

What is the value of 1 mole 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 the formula for a mole?

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).

What is a mole ratio?

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 KG mole?

One kg-mol (or one kilo mole) is the molecular mass of the substances expressed in kilogram. We know that in CGS system one g-mole of substances contain Avogadro no of particles (6. 023×1023) and in SI system one kg-mol substance contains Avogadro no of particles (6.

What is mole with example?

A mole corresponds to the mass of a substance that contains 6.023 x 1023 particles of the substance. The mole is the SI unit for the amount of a substance. Its symbol is mol. By definition: 1 mol of carbon-12 has a mass of 12 grams and contains 6.022140857 x 1023 of carbon atoms (to 10 significant figures). Examples.

What is mole in human body?

Moles occur when cells in your skin grow in a cluster instead of being spread throughout the skin. Most moles are made of cells called melanocytes, which make the pigment that gives your skin its natural color.

Why is mole concept important?

Explanation: THE mole is important because it allows chemist to work with a subatomic world with macro world units and amount. Atoms molecules and formula units are very small and very difficult to work with usually. However the mole allows a chemist to work with amount large enough to use.
