Questions & Step-by-Step Solutions

How many molecules are in 0.25 moles of oxygen gas (O2)? (2022)
  • Step 1: Understand that 1 mole of any substance contains Avogadro's number of molecules, which is approximately 6.022 x 10^23.
  • Step 2: Identify how many moles of oxygen gas (O2) you have, which is 0.25 moles in this case.
  • Step 3: Use the formula to find the number of molecules: Number of molecules = moles x Avogadro's number.
  • Step 4: Plug in the values: Number of molecules = 0.25 moles x 6.022 x 10^23 molecules/mole.
  • Step 5: Calculate the result: 0.25 x 6.022 = 1.5055, and keep the exponent the same, so you get 1.5055 x 10^23 molecules.
