Which of the following does NOT contain Avogadro's number of particles?

Question

Quizplus · Accepted Answer

Avogadro's number represents the number of particles in 1 mole of a substance. To determine if a given amount of substance contains Avogadro's number of particles, one can use dimensional analysis and convert the given amount into moles. Only option D, 12 g of water, does not contain Avogadro's number of particles because it corresponds to only 2/3 of a mole of water (using the molar mass of water, 18 g/mol). A and B both correspond to 1 mole of substance, and C corresponds to 6.02 × 10²³ atoms of aluminum, which is Avogadro's number of particles for that element.
