Quizplus · Accepted Answer

One mole of any substance contains Avogadro's number of particles, which is approximately 6.02 x 10^23. Therefore, 4.00 moles of Cl₂ would contain: 4.00 mol x 6.02 x 10^23 molecules/mol = 2.408 x 10^24 molecules This matches answer choice B, which is 2.41 x 10^24 written in scientific notation.
