Answer to Question #119756 in Chemistry for aljoc

Question

What is the pressure required to compress hydrogen at 1.00 atm from 300.0 mL to 200.0 mL at a constant temperature?

Answer 1

P₁ = 1.00 atm

V₁ = 300.0 mL

P₂ = unknown

V₂ = 200.0 mL

T = constant

Solution:

Since the temperature doesn't change, Boyle's law can be used.

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

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

P₂ = P₁V₁ / V₂

P₂ = (1.00 atm × 300.0 mL) / ( 200.0 mL) = 1.5 atm

P₂ = 1.5 atm

Answer: 1.5 atm is the pressure required to compress hydrogen.
