Question

If a sample of N2 gas has an initial pressure of 500 Torr and volume of 0.5 L, what will the final volume be if the pressure is increased to 700 Torr?

Answer 1

V₂ = 0.4 L

Step-by-step explanation:

Data:

• P₁ (initial pressure) = 500 torr
• V₁ (initial volume) = 0.5 L
• P₂ (final pressure) = 700 torr

Wanted:

• V₂ (final volume)

Equation:

• P₁V₁ = P₂V₂ → V₂ = P₁V₁ / P₂

Solution:

• V₂ =
  `((500 torr)(0.5 L))/(700 torr)` = 0.3571 L or 0.4 L
