<h3>What is an ideal gas equation?</h3>The ideal gas equation, pV = nRT, is an equation used to calculate either the pressure, volume, temperature or number of moles of a gas.
Given data:
= 720 mmHg
= ?
= 2.5 mol
= 3.2 mol
= 34 L
= 45 L
Formula
Combined gas law
= 696.32 mmHg
Hence, 696.32 mmHg is the final pressure of the gas.
