In a closed bottle are a certain number of hydrogen molecules.In an identical closed bottle at the same temperature and internal pressure are a certain number of nitrogen molecules.The bottle with the greater number of molecules is the one containing
A)hydrogen.
B)nitrogen.
C)both the same

Question

Quizplus · Accepted Answer

The number of molecules in a gas depends on its volume, temperature, and pressure, according to the ideal gas law. Assuming the two bottles have the same volume and pressure, the number of molecules in each bottle would be proportional to their temperature (in Kelvin). Since the temperature is the same for both bottles, it follows that the number of hydrogen and nitrogen molecules would be the same. Therefore, answer choice C) "both the same" is correct.

In a Closed Bottle Are a Certain Number of Hydrogen
