Which of the following statements about "one-half mole of H 2 O" is incorrect?

The mass of one-half mole of a substance depends on its molar mass, which varies between different substances. H 2 O and CCl 4 have different chemical formulas, thus different molar masses, so their masses in grams per one-half mole would not be the same.
