How many moles of chlorine (cl) atoms are in a sample of 1.72 × 1022 atoms?
a. 0.0286 mol cl
b. 35.0 mol cl
c. 1.03 × 1023 mol cl
d. 1.04 × 1046 mol cl

0.0286 mol Cl

Explanation:

to convert atoms to moles, we need Avogadro's number.

1 mol= 6.02 x 10^23 atoms

1.72 x 10^22 atoms (1 mol/ 6.02 x 10^23)= 0.0286 moles

solute : a solute is a substance that is dissolved in another substance is known as a solvent. it is mixed with a special mixture know as homogeneous mixture.

solvent: a solvent is a substance that dissolved a solute, which results in a solution is known as solvent.

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