How many moles of neon are found in 2.22 x 10^28 rp

0.37× 10⁵ moles of neon

Explanation:

Given data:

Number of atoms of neon = 2.22 × 10²⁸

Number of moles = ?

Solution:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

For example,

18 g of water = 1 mole = 6.022 × 10²³ molecules of water

For 2.22 × 10²⁸ atoms:

2.22 × 10²⁸ atoms × 1 mol / 6.022 × 10²³ atoms

0.37× 10⁵ moles of neon
