For many purposes we can treat ammonia NH3 as an ideal gas at temperatures above its boiling point of ?33.°C . Suppose the temperature of a sample of ammonia gas is lowered from 19.0°C ? to ?14.0°C , and at the same time the pressure is changed. If the initial pressure was 3.5atm and the volume decreased by 35.0% , what is the final pressure? Round your answer to the correct number of significant digits. atm
