Gases

• What is the relationship between the amount of gases and the volume they occupy under the same conditions of temperature and pressure?

  Equal amounts of gases occupy the same volume under the same conditions.
• What is the volume of 1 mole of any gas at room temperature and pressure (RTP)?

  24 dm³
• What are the standard conditions defined as for RTP?

  20 degrees Celsius and 1 atmosphere pressure.
• What equation relates the volume of gas at RTP to the number of moles?

  Volume of gas (dm³) at RTP = Moles x 24
• How can you calculate the volume of gas produced at RTP if you know the moles produced?

  Multiply the moles by 24 to get the volume produced.
• If 5 moles of hydrogen are produced at RTP, what is the volume produced?

  120 dm³
• What is the significance of RTP in gas calculations?

  • Standardizes conditions for gas measurements
  • Allows for consistent calculations of gas volumes
  • Facilitates comparisons between different gases
