In 2 sentences or less describe why Amagats Law is superior

In 2 sentences or less, describe why Amagat\'s Law is superior to Dalton\'s Law when determining the compressibility factor for a real gas mixture.

Solution

Dalton\'s law is an adequate approximation up to 100 atm but it fails thereafter, whereas Amagat\'s law provides an excellent approximation for pressures even exceeding 1000 atm. Thus, Amagat\'s law is superior.
