A .332 mold sample of gas at a constant pressure and temperature has a volume of 150.0mL. If the volume of the gas is decreased to 50.0mL, how many moles of the gas will remain

Answer:

0.111 mol

Explanation:

We can solve this problem by using Avogadro's law, which states that at constant pressure and temperature:

  • V₁n₂=V₂n₁

Where in this case:

  • V₁ = 150.0 mL
  • n₂ = ?
  • V₂ = 50.0 mL
  • n₁ = 0.332 mol

We input the data given by the problem:

  • 150.0 mL * n₂ = 50.0 mL * 0.332 mol

And solve for n₂:

  • n₂ = 0.111 mol
