Answer to Question #139692 in Chemistry for Nielle

Question

A sample of chlorine gas has a volume of 6 liters at a temperature of 10 °C. What volume does the gas occupy at 50 °C?

Answer 1

V₁ = 6 L

T₁ = 10°C = 283 K

V₂ = unknown

T₂ = 50°C = 323 K

P = const

Solution:

Since the pressure doesn't change, Charle's law can be used.

Charle's law law can be expressed as: V₁/T₁ = V₂/T₂

To find the final volume, solve the equation for V₂:

V₂ = V₁T₂ / T₁

V₂ = (6 L × 323 K) / (283 K) = 6.848 L = 6.85 L

V₂ = 6.85 L

Answer: A sample of chlorine gas occupy 6.85 L at 50 °C.
