WebThe Ideal Gas Law is an equation of state for a gas, which describes the relationships among the four variables temperature (T), pressure (P), volume (V), and moles of gas … WebThe answer is False. If you solve the Ideal Gas equation for n (the number of particles expressed as moles) you get: n = PV/RT. Thus, at STP, the same volume of all gases have the same number of molecules (provided the conditions are suitable for the Ideal Gas Law to apply). A more dense gas has more MASSIVE molecules, but the same number of ...
