Questions & Step-by-Step Solutions
If 1 mole of an ideal gas occupies 22.4 L at STP, what is the pressure exerted by the gas?
Correct Answer: 1 atm
Step 1: Understand what STP means. STP stands for Standard Temperature and Pressure, which is defined as 0 degrees Celsius (273.15 K) and 1 atmosphere (atm) of pressure.
Step 2: Know that at STP, 1 mole of an ideal gas occupies a volume of 22.4 liters.
Step 3: Recognize that the question is asking for the pressure exerted by the gas at STP.
Step 4: Recall that at STP, the pressure of the gas is defined to be 1 atm.
Step 5: Conclude that the pressure exerted by the gas is 1 atm.
Ideal Gas Law – Understanding the behavior of ideal gases under standard conditions, specifically the relationship between volume, pressure, and temperature.
Standard Temperature and Pressure (STP) – Recognizing the conditions defined as STP, which are 0 degrees Celsius (273.15 K) and 1 atm pressure.
