Define one mole , Avogadro number and gram atomic mass

Open in App

Solution

One mole is the number of atom s in precisely 12 thousandths of a kilogram (0.012 kg) of C-12, the most common naturally-occurring isotope of the element carbon.This number is equal to approximately 6.022169 x 10 ^23.

This number ie, 6.022169 x 10 ²³ is known as the Avogadro number.

Gram atomic mass is the mass of one mole of an element. ... So, for example, sodium (Na) has an atomic weight of 22.99 u, so it has a gram atomic mass of 22.99 grams. So one mole of sodium atoms has a mass of 22.99 g.
