I had the same question, it's most likely B.
Answer:
This question is to vague. PS: what are you talking about?

The answer is (3) 11.2 L of N2(g). When the choices are all gases, the number of molecules depends on the molar number of the gas. Under the condition of STP, the molar number of a gas is depends on volume only. So the same volume of gas has the same number of molecules.
Answer:
1) ) CBr₄ has a higher boiling point than CCl₄: True
2 CBr₄ has weaker intermolecular forces than CCl₄: False
3) CBr₄ has a higher vapor pressure at the same temperature than CCl₄: False
4) CBr₄ is more volatile than CCl₄: False
Explanation:
1) ) CBr₄ has a higher boiling point than CCl₄: True :
Due to higher molecular weight CBr₄ has more london disperion forces thus making the intermolecular interactions stronger and thus it need more temperature to boil it off.
2 CBr₄ has weaker intermolecular forces than CCl₄: False
Due to higher molecular weight CBr₄ has more london disperion forces thus making the intermolecular interactions stronger.
3) CBr₄ has a higher vapor pressure at the same temperature than CCl₄: False
Due to higher molecular weight CBr₄ has more london disperion forces thus making the intermolecular interactions stronger. Thus the vapor pressure of it will be less than CCl₄ at the same temperature.
4) CBr₄ is more volatile than CCl₄: False
Due to higher molecular weight CBr₄ has more london disperion forces thus making the intermolecular interactions stronger. Thus CCl₄ is more volatile.
