How many moles are in 1.02 x 10^23 atoms of argon gas

0.17 mol

Explanation:

Given data:

Number of atoms of Ar gas = 1.02×10²³ atom

Number of moles = ?

Solution:

The given problem will solve by using Avogadro number.

The number 6.022 × 10²³ is called Avogadro number.

1 mole = 6.022 × 10²³ atoms

1.02×10²³ atom × 1 mol / 6.022 × 10²³ atoms

0.17 mol

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 electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.
