Question

Two flasks $A$ and $B$ of $500$ mL each are respectively filled with $O_2$ and $S{O}_2$ at $300$K and $1$ atm pressure. The flasks contain:

• A. the same number of atoms
• B. the same number of molecules
• C. more number of moles in flask $A$ as compared to flask $B$
• D. the same mass of gases

Answer 1

Answer: (A)

the same number of atoms

According to Avogadro's Hypothesis: Equal volumes of all gases contain equal number of atoms under similar conditions of temperature and pressure. So, the correct option will be '$A$'.
