A 2.0 L sample of dry air in a cylinder exerts a pressure of 3.0 atm at a temperature of 25 degrees Celsius. Without a change in temperature, a
piston is moved until the pressure in the cylinder is reduced to 2.0 atm.
What is the volume of the gas? Record your answer exactly like the given
volume of 2.0 L (2 digits) followed by a space then the unit using a capital
letter.

pls help due end of the day
