PLSSSSSSSS help !!!!! One mole of an element contains which of the following?
irina [24]

Answer:

6.02 × 10²³ atoms

Explanation:

The number 6.02 × 10²³ is called Avogadro number. It is the number of atoms,  ions and molecules in one gram atoms of an element, one gram ions of substance and one gram molecule of a compound.

For example:

32 g of oxygen = one mole = 6.02 × 10²³  atoms O.

1.008 g of hydrogen = one mole = 6.02 × 10²³  atoms of H.

or

18 g of H₂O =one mole = 6.02 × 10²³  molecules of H₂O

44 g of CO₂ = one mole = 6.02 × 10²³  molecules of CO₂

or

62 g of NO₃⁻ = one mole of NO₃⁻ = 6.02 × 10²³  ions of NO₃⁻
