Answer:

In the explanation :)

Explanation:

A balanced chemical equation follows law of conservation of mass. This law states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form. This means that total mass on the reactant side is equal to the total mass on the product side.

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
