Answer to Question #307910 in General Chemistry for cols

Question

What is the temperature of an 11.2 L sample of carbon monoxide, CO, at 744 torr if it occupies 13.3 L at 55°C and 744 torr?

Answer 1

The pressure is constant, so we can use Charles’ Law:

 V₁/T₁ = V₂/T₂

Invert both sides of the equation:

T₁/V₁ = T₂/V₂

Multiply both sides by V₂:

T₂ = T₁ x V₂/V₁

V₁ = 13.3 L; T₁ = (55 + 273.15) K = 328.15 K

V₂ = 11.2 L; T₂ = ?

T₂ = 328.15 K x 11.2 L/13.3 L = 276 K = 3°C
