Two beakers contain equal masses of [tex]CCl_4[/tex] and [tex]NH_3[/tex], respectively. Which beaker contains more molecules?

1. The beaker with [tex]CCl_4[/tex]
2. The beaker with [tex]NH_3[/tex]
3. The two beakers contain the same number of molecules

Answer :

Final answer:

Given equal masses of CCl4 and NH3, the beaker with NH3 contains more molecules because NH3 has a lower molar mass, leading to a greater number of moles and molecules. So , correct option is 2) The beaker with NH₃

Explanation:

The question deals with determining which beaker contains more molecules, given that each has an equal mass of CCl4 (carbon tetrachloride) and NH3 (ammonia), respectively. To answer this, we need to look at the molar mass of each compound and use Avogadro's law, which states that equal volumes of gases at the same temperature and pressure contain the same number of molecules.

Although Avogadro's law directly applies to gases, the principle that the number of molecules is directly proportional to the number of moles can be extended to substances in other states by considering their molar mass. Here, the molar mass of CCl4 is approximately 153.81 g/mol, and the molar mass of NH3 is approximately 17.03 g/mol. Since each beaker contains an equal mass of each substance, the beaker with NH3 will have more moles, and hence more molecules, because NH3 has a lower molar mass.

So, the answer is: The beaker with NH3 contains more molecules.
