What volume of sulfur trioxide gas,SO₃,has the same number of atoms as 4 L of helium gas at the same temperature and pressure? A)20 L B)0.8 L C)4 L D)1 L E)16 L

Question

Quizplus · Accepted Answer

The Avogadro's Law states that equal volumes of gases at the same temperature and pressure contain equal number of molecules. Since sulfur trioxide gas (SO3) has 4 atoms (one sulfur and three oxygen atoms) in a molecule, it means that it contains 4 times the number of molecules as compared to helium gas, which has only one atom per molecule. Therefore, the volume of SO3 gas that has the same number of atoms as 4 L of helium gas would be 1 L.
