Answer to Question #327572 in General Chemistry for jazzy

Question

a gas with a pressure of 845 torrs occupies 11. o l what will the pressure be for a volume of 2.50 l if the temperature remains constant

Answer 1

P₁ = 845 torr

V₁ = 11.0 L

T₁ = T₂ = constant

P₂ = ???

V₂ = 2.50 L

Solution:

Since the temperature and amount of gas remain unchanged, Boyle's law can be used.

Boyle's gas law can be expressed as: P₁V₁ = P₂V₂

To find the new pressure, solve the equation for P₂:

P₂ = P₁V₁ / V₂

P₂ = (845 torr × 11.0 L) / (2.50 L) = 3718 torr

P₂ = 3718 torr

Answer:  The pressure will be 3718 torrs
