Please indicate question number for each answer
Please do which ever ones you can but if you can do most of them or all of them i will give you Brainliest..

1) When a container of hydrogen gas is compressed to 240 mL, the pressure increases from 1 atm to 12 atm. What was the original volume of the sample?

2) A flexible 4.00 L container of nitrogen gas at a pressure of 15 atm was allowed to expand to a volume of 10.0 L. If the temperature remains constant, what would the new pressure be in the container?

3) A container of argon gas has a volume of 8.00 L at a temperature of 300 K. What volume does the gas occupy at 400 K?

4) Alyssa bought a 2.0 liter size birthday balloon at Meijer, where the temperature was 300 K. When she took it outside, the volume of the balloon dropped to 1.5 liters. What was the temperature outside, in Kelvins?

5) A driver fills their tires to a pressure of 2.00 atm when the temperature outside was 300 K. What was the new pressure in the tires when the outdoor temperature drops to 270 K?

6) A container of neon gas exerts a pressure of 1.20 atm when the temperature is 300 K. What pressure is produced when the temperature is raised to 450 K?

7) At what Kelvin temperature will a sample of gas have a pressure of 3.90 atm when the same sample has a pressure of 1.50 atm at 200 K?

8) Two mol of methane gas at 250 K has a pressure of 5 atm. What is the volume of the gas?

9) An unknown gas has a volume of 5.0 liters when at a temperature of 310 K and a pressure of 0.9 atm. How many moles of gas would this be?

10) Antoine Lavoisier was experimenting with the different gases a plant needed to survive. He added 0.65 atm of oxygen to the container holding the plant, as well as 0.25 atm of carbon dioxide and 0.20 atm of water vapor. What was the total pressure in the container?

11) The total pressure in a room at sea level is 101.3 kPa. If the partial pressure of carbon dioxide is 0.1 kPa, nitrogen is 80 kPa and other minor gases have a combined partial pressure of 0.2 kPa, what is the partial pressure of the oxygen?

12) A balloon contains three gases, oxygen (O2), helium (He), and nitrogen (N2). Which gas will leak (effuse) out of the balloon the most quickly?
