A sample of carbon dioxide gas at 398.15 K and 248 torr occupies a volume of 275 mL. What will be temperature needed to increase the volume to 0.321 L while pressure remains constant?

T₂ = 464.75 K

Explanation:

Given dа ta:

Initial Temperature = 398.15 K

Pressure = 248 torr (constant)

Initial Volume = 275 mL (275/1000 = 0.275 L)

Final volume = 0.321 L

Final temperature = ?

Solution:

V₁/T₁ = V₂/T₂

T₂ = V₂ T₁ / V₁

T₂ = 0.321 L * 398.15 K / 0.275 L

T₂ = 127.81 L. K / 0.275 L

T₂ = 464.75 K
