Questions & Step-by-Step Solutions

If 1 mole of a gas occupies 22.4 L at STP, how much volume will 0.5 moles occupy?
Correct Answer: 11.2 L
  • Step 1: Understand that 1 mole of gas occupies 22.4 liters at STP (Standard Temperature and Pressure).
  • Step 2: Identify how many moles of gas you have, which is 0.5 moles.
  • Step 3: Use the formula to find the volume: Volume = moles x volume per mole.
  • Step 4: Substitute the values into the formula: Volume = 0.5 moles x 22.4 L/mole.
  • Step 5: Calculate the volume: 0.5 x 22.4 = 11.2 L.
  • Molar Volume of a Gas – At standard temperature and pressure (STP), one mole of an ideal gas occupies 22.4 liters.
  • Stoichiometry – The calculation of reactants and products in chemical reactions, including the use of mole ratios.
