How many atoms of chlorine are in 1.00 mol of chlorine gas?

##1.2*10^24## atoms of chlorine

Chlorine gas (##Cl_2##) has two atoms of elemental chlorine in a molecule, so: ##1## mol of ##Cl_2## have ##6*10^23## molecules of ##Cl_2## ##1## molecule of ##Cl_2## have ##2## atoms per molucule Then ##2*6*10^23 = 1.2*10^24## atoms of chlorine in a mol of chlorine gas
