alleryAvogadro's law says equal volumes of all gases at equal temperature and pressure hold the same number of:
AMinutes
BMixtures
CMaterials
DMolecules
Answer & Solution
Correct answer: D. Molecules
1. The law compares gases by volume, not by mass.
2. What it equates is a count.
3. Equal volumes of all gases at equal temperature and pressure have the same number of molecules.
4. So the answer is molecules.
