Gas Laws Homework
Master Gas Laws! Solve volume, pressure, & mole problems.
1.) A 325 mL sample of air has a pressure of 720 torr at 30 °C. What volume will the gas occupy at 900 torr and 60 °C? 2.) A quantity of oxygen, O2, gas occupies a volume of 17.7 L at STP. How many moles of oxygen are present? What would the mass be? 3.) A gas sample is collected over water at 25 °C. If the pressure in the room was 1.05 atm, what was the pressure of the gas? (Pwater = 0.03 atm) 4.) A balloon is filled with helium gas and another is filled with nitrogen gas. Which balloon will deflate faster?
