A sample of nitrogen occupies 10.0 liters at 25°c and 98.7 kpa. What would be the volume at 20°c and 102.7 kpa?
Fynjy0 [20]

Answer:

  •    9.4 liter

Explanation:

<u>1) Data:</u>

  •  V₁ = 10.0 L
  •  T₁ = 25°C = 25 + 273.15 K = 298.15 K
  •   P₁ = 98.7 Kpa
  •   T₂ = 20°C = 20 + 273.15 K = 293.15 K
  •    P₂ = 102.7 KPa
  •    V₂ = ?

<u>2) Formula:</u>

Used combined law of gases:

  •    PV / T = constant

  •    P₁V₁ / T₁ = P₂V₂ / T₂

<u>3) Solution</u>:

Solve the equation for V₂:

  •    V₂ = P₁V₁ T₂ / (P₂ T₁)

Substitute and compuite:

  • V₂ = P₁V₁ T₂ / (P₂ T₁)

  • V₂ = 98.7 KPa × 10.0 L × 293.15 K / (102.7 KPa × 298.15 K)

  • V₂ =  9.4 liter ← answer
