If you are inflating a balloon that has 0.0200 mol of Helium and a volume of 0.150 m3. How many moles of Helium are there if the new volume of the balloon is 0.90 m3?

Pls help

Respuesta :

Answer:

1.2 moles of Helium

Explanation:

According to Avogadro's Law :

  • V₁/n₁ = V₂/n₂

Here :

  1. V₁ = 0.15 m³
  2. n₁ = 0.2 moles
  3. V₂ = 0.9 m³

Solving :

  • n₂ = V₂n₁/V₁
  • n₂ = 0.9 x 0.2 / 0.15
  • n₂ = 6 x 0.2
  • n₂ = 1.2 moles of Helium
