ASAP PLSSS How many atoms of strontium are in a sample of 33.6 mol strontium? 1) 4.22 x 1023 atoms Sr

2) 4.22 x 1024 atoms Sr

3) 2.02 x 1025 atoms Sr

4) 2.02 x1023 atoms Sr

33.6 mol of the atom strontium contains approximately

3) 2.02 × 10²⁵ atoms of strontium

Explanation:

The number of atoms in one mole of a substance is given by Avogadro's number number, , which is presented as follows;

1 mole of a substance contains = 6.022 × 10²³ elementary particles

33.6 mol of a substance will contain 33.6 × 6.02214 × 10²³ elementary particles of the substance

Therefore;

33.6 mol of the atom strontium contains 33.6 × 6.02214 × 10²³ = 2.023439 × 10²⁵ atoms of strontium

33.6 mol of the atom strontium contains ≈ 2.02 × 10²⁵ atoms of Sr.
