Questions & Step-by-Step Solutions

If 0.5 moles of a gas occupy 11.2 liters at STP, what is the molar volume of the gas?
  • Step 1: Understand that STP means Standard Temperature and Pressure, where 1 mole of any gas occupies 22.4 liters.
  • Step 2: Note that you have 0.5 moles of gas and it occupies 11.2 liters.
  • Step 3: Realize that the molar volume is the volume occupied by 1 mole of gas at STP, which is always 22.4 liters.
  • Step 4: Conclude that regardless of how many moles you have, the molar volume of the gas at STP is 22.4 liters.
  • Molar Volume at STP – At standard temperature and pressure (STP), one mole of an ideal gas occupies 22.4 liters.
  • Gas Laws – Understanding the relationship between moles, volume, and conditions of temperature and pressure.
