1. Carbon dioxide gas has an initial pressure of 650 mmHg and an initial volume of 0.50 L. At constant temperature and in a closed-system, what is the pressure (in atm) when the volume of the sample is decreased to 125 mL? 2. Under constant pressure, a sample of hydrogen gas initially at 88.0 °C and 9.40 L is cooled until its final volume is 2.50 L. What is its final temperature in the unit of Kelvin? 3. Given that 35.5 g of carbon monoxide are present in a container if volume 250 mL. What is the pressure of the gas (in atm) if the temperature is 55 °C. 4. What volume is occupied by 15.5 g of argon gas at a pressure of 820 mmHg and a temperature of 50.0 °C? Would the volume be different if the sample were 15.5 g of chlorine gas (under identical conditions)?
