Answer to Question #345396 in General Chemistry for nora

Question

chlorine gas occupies a volume of 350mL with a pressure of 720 torr. what will the new volume be at standard pressure?

Answer 1

Given:

P₁ = 720 torr

V₁ = 350 mL

T = constant

P₂ = standard pressure = 760 torr

V₂ = unknown

Formula: P₁V₁ = P₂V₂

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 volume, solve the equation for V₂:

V₂ = P₁V₁ / P₂

V₂ = (720 torr × 350 mL) / (760 torr) = 331.6 mL

V₂ = 331.6 mL

Answer: The new volume will be 331.6 mL
