Question

the relationships among which variable quantities are expressed by the ideal gas law equation? (1 point)
pressure, volume, number of moles, mass
pressure, volume, temperature, molar mass
pressure, volume, temperature, number of moles
volume, temperature, number of moles, gas constant

Explanation:

The ideal gas law is expressed as $PV = nRT$, where $P$ is pressure, $V$ is volume, $n$ is the number of moles, $T$ is temperature, and $R$ is the gas - constant (a fixed value). So the equation relates pressure, volume, temperature, and number of moles.

Answer:

C. pressure, volume, temperature, number of moles
