The correct Answer is:
To solve the question, we will analyze the assertion and reason provided. ### Step 1: Understand the Assertion The assertion states that "At the same temperature and pressure, equal volumes of all gases contain equal numbers of molecules." This statement is based on Avogadro's law, which states that equal volumes of gases at the same temperature and pressure contain an equal number of molecules. ### Step 2: Analyze the Reason The reason provided states that "In 1 L at NTP, the total number of molecules is `6.02 x 10^23`." This statement is misleading. At Normal Temperature and Pressure (NTP), one mole of any gas occupies a volume of 22.4 liters, not 1 liter. Therefore, the total number of molecules in 22.4 liters at NTP is `6.022 x 10^23`, which corresponds to one mole of gas. ### Step 3: Conclusion - The assertion is **true** because it correctly reflects Avogadro's law. - The reason is **false** because it incorrectly states the volume at which the number of molecules is given. Thus, the correct answer is that the assertion is true, but the reason is false. ### Final Answer Assertion: True Reason: False ---
