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

0.37 * 10⁵ moles of neon

Explanation:

Given dа ta:

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
