To answer this item, we are to think that the given gas behaves ideally such that the equation,

PV = nRT

where P is the pressure, V is volume, n is the number of moles, R is the universal gas constant, and T is the temperature. When all things are equal aside from V and T, the equation becomes,

V1T2 = V2T1

Substituting the known values,

(2.5 L) (334 K) = (V2) (298 K)

The value of V is equal to 2.8 L.

Answer: 2.8 L.
