Question

Quizplus · Accepted Answer

In the equation pV = nRT, 
- P is the pressure of the gas, measured in atmospheres (atm), 
- V is volume of the gas, measured in liters (L), 
- n is the number of moles of the gas, measured in moles (mol), 
- T is the temperature of the gas, measured in kelvin (K), and 
- R is the ideal gas constant, with a value of 0.0821 L atm / mol K, which is the same for all gases.

Therefore, the correct choice is D, as n represents the number of moles of gas in the equation.
