Question

Sample equal to the atomic mass of an element in grams contains

________ atoms. This amount of matter is called _________ .

Answer 1

Sample equal to the atomic mass of an element in grams contains 6.02214179 × 10²³ atoms. This amount of matter is called a mole

Step-by-step explanation:

Experimentally, it has been determined that 1 mole of any substance contains 6.02214179 × 10²³ elementary entities. The number of elementary entities in the mole is known as Avogadro's number,
`N_A`, or the Avogadro's constant and the unit of the constant is per mole

The molar mass of a compound or an element is the mass of 1 mole of the compound or the element given in grams

Similarly, the gram atomic mass is the mass in grams of 1 mole of the atoms of the element that contains one Avogadro's number of atoms

Therefore, we have;

The number of atoms in a sample equal to the atomic mass of an element in grams = 6.02214179 × 10²³ atoms

The name given to the amount of matter containing equivalent to 6.02214179 × 10²³ elementary particles = A mole.
