What is the constant volume of the gas under Ideal Gas Law?*1 pointA. 0.0821 LB. 1.0 LC. 22.4 LD. 273.15 L

Break Down the Problem

1. Identify the constants and values in the Ideal Gas Law.
2. Recall the specific volumes associated with ideal gases at standard conditions.

Relevant Concepts

The Ideal Gas Law is given by the equation: $PV = nRT$ where:

• $P$ = pressure
• $V$ = volume
• $n$ = number of moles of gas
• $R$ = ideal gas constant
• $T$ = temperature in Kelvin

Analysis and Detail

At standard temperature and pressure (STP), one mole of an ideal gas occupies a volume of approximately 22.4 liters (L). This is a commonly known result and represents the volume of any ideal gas at STP.

Verify and Summarize

Here the options provided need evaluating against the well-known constant volume of gas under the Ideal Gas Law at STP:

• A. 0.0821 L is related to the Ideal Gas Constant $R$ but not a constant volume.
• B. 1.0 L is not the standard constant volume for one mole of gas.
• C. 22.4 L is the volume of one mole of an ideal gas at STP.
• D. 273.15 L is the temperature in Kelvin at standard conditions.

Final Answer

The constant volume of the gas under Ideal Gas Law is C. 22.4 L.
