Part 1: Determine what equation(s) you would need for each of the following problems
1. 50.0 liters of a gas are prepared at 720.0 mm Hg and 100.0 °C. The gas is placed into a tank under high pressure.
When the tank cools to 30.0 °C, the pressure of the gas is 28.0 atm. What is the volume of the gas?
