As you increase elevation the atmospheric pressure decreases, which means the boiling point of water also decreases. In Denver, the Mile High City, the boiling point of water is 95.0°C. a. How many grams of your assigned salt (using the van't Hoff factor you calculated in lab) would need to be added to 1.0 gallon (3.8 kg) of water to raise the temperature to 100.0°C, the boiling point of water at sea level.
