Consider two equal-volume flasks of gas at the same temperature and pressure. One gas, oxygen, has a molecular mass of 32. The other gas, nitrogen, has a molecular mass of 28. What is the ratio of the number of oxygen molecules to the number of nitrogen molecules in these flasks?
A) $\frac { 32 } { 38 }$
B) $\frac { 28 } { 32 }$
C) $\sqrt { \frac { 28 } { 32 } }$
D) $\sqrt { \frac { 32 } { 28 } }$
E) $\frac { 1 } { 1 }$

Quizplus · Accepted Answer

According to Avogadro's law, equal volumes of gases at the same temperature and pressure contain the same number of molecules. Therefore, the ratio of the number of oxygen molecules to the number of nitrogen molecules is 1:1.
