Answer:
28.82 mL
Explanation:
This is about gases laws, in this case about Charles Gay Lussac.
At constant pressure the volume is proportional to the T°.
V₁ / T₁ = V₂ /T₂
42.1 mL / 371K = V₂ /254K
(42.1 mL / 371K) . 254K
V₂ = 28.82 mL
In conclussion:
As T° was decreased, the volume also decreased too.
