• A. P1V1 = P2V2
• B. PV = k
• C. PV = nRT
• D. V/T = k

Answer: (C)

Verified step by step guidance

1. Identify the Ideal Gas Law from the given options. The Ideal Gas Law is a fundamental equation in chemistry that relates the pressure, volume, temperature, and amount of gas.
2. Recall the formula for the Ideal Gas Law: $PV=nRT$, where P is pressure, V is volume, n is the number of moles, R is the ideal gas constant, and T is temperature.
3. Examine each given equation to determine which one matches the Ideal Gas Law formula. The options are: $P_1{V}_1=P_2{V}_2$, $PV=k$, $PV=nRT$, and $\frac{V}{T}=k$.
4. Recognize that the equation $PV=nRT$ is the Ideal Gas Law, as it includes all the necessary variables: pressure (P), volume (V), number of moles (n), ideal gas constant (R), and temperature (T).
5. Conclude that the correct representation of the Ideal Gas Law from the given options is $PV=nRT$.
