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 17.0°C to −21.0°C, and at the same time the pressure is changed. If the initial pressure was 0.17kPa and the volume increased by 60.0%, what is the final pressure? Round your answer to the correct number of significant digits.
