Question

The relationships among which quantities are expressed by the ideal gas law equation?

volume, temperature, number of moles, gas constant
pressure, volume, temperature, molar mass
pressure, volume, number of moles, mass
pressure, volume, temperature, number of moles

Answer 1

The relationships among the quantities expressed by the ideal gas law equation are:

**pressure, volume, temperature, number of moles.**

The ideal gas law is commonly written as:

\[ PV = nRT \]

where:
- \( P \) = pressure,
- \( V \) = volume,
- \( n \) = number of moles,
- \( R \) = gas constant, and
- \( T \) = temperature.
