The perfect gas equation is PV = nRT where n is the _____.

1. number of moles
2. amount of gas
3. volume of gas
4. pressure of gas

Answer: 1. number of moles

Explanation: The perfect gas equation or the ideal gas equation is simply expressed as

PV = nRT

The four gas variables in the equation are pressure (P), volume (V), the number of mole of gas (n), and temperature (T). R is the gas constant.
