Answer

Answer:

A. the temperature of the gas

Explanation:

Step1: Recall ideal gas law

The ideal gas law is $PV = nRT$, where $P$ is pressure, $V$ is volume, $n$ is the number of moles, $R$ is the universal gas constant, and $T$ is temperature.

Step2: Solve for $R$

We can rewrite the ideal - gas law to solve for $R$ as $R=\frac{PV}{nT}$. Given $P$, $V$, and $n$, we need $T$ (temperature) to calculate $R$.
