How many chloride ions are there in 3.00 mol of aluminum chloride?

Question

Quizplus · Accepted Answer

Aluminum chloride (AlCl3) consists of one aluminum ion and three chloride ions. Therefore, for every mole of AlCl3, there are three moles of chloride ions. For 3.00 moles of AlCl3, this results in 3.00 * 3 = 9.00 moles of chloride ions. Since one mole of any substance contains Avogadro's number of entities (6.022 × 10^23), 9.00 moles of chloride ions contain 9.00 * 6.022 × 10^23 = 5.42 × 10^24 chloride ions.
