Question

Define Mole, A.M.U, Avogadro numbers????

Answer 1

hey dear your answer




Avogadro's number is a proportion that relates molar mass on an atomic scale to physical mass on a human scale. Avogadro's number is defined as the number of elementary particles (molecules, atoms, compounds, etc.) per mole of a substance. It is equal to 6.022×1023 mol-1 and is expressed as the symbol NA.

Answer 2

Avogadro's number is defined as thenumber of elementary particles (molecules, atoms, compounds, etc.) per mole of a substance. It is equal to 6.022×1023 mol-1 and is expressed as the symbol NA.

Amu (atomic mass unit) : the standard unit of measurement of atomic mass. Avogadro's number : the number of units in one mole: 6.022 × 1023, which is the number of atoms in 12 grams of carbon-12. molar mass : the mass of one mole of a substance, measured in grams.

The mole is defined as the amount of substance containing the same number of chemical units (atoms, molecules, ions, electrons, or other specified entities or groups of entities) as exactly 12 grams of carbon-12.
