CeCl molar mass = 168.36 g/mol

Cl molar mass = 35.45 g/mol


(35.45/168.36) x 100 = 21.06%

CeCl should be CsCl. Just a typo to be sure. Molar mass is correct as is the answer.

Ha! Maybe I should be nicer (more patient) with my students when they make this type of error! Thanks for the correction. By the way, I follow your answers because they are so clear and accurate, even on tough problems.
