    0.177L

    Explanation:

    For this, we can use the combined gas law

    (P1*V1) / T1 = (P2*V2) / T2

    where

    P1 (initial pressure) = 1.25 atm

    V1 (initial volume) = 0.254L

    T1 (initial temperature in Kelvin) = 298K

    P2 (final pressure) = 1.67 atm

    V2 (final volume) = ?

    T2 (final temperature in Kelvin) = 278K

    Since we are trying to find the final volume, we can rearrange the above equation to make V2 the subject.

    V2 = (((P1*V1) / T1) * T2) / P2

    V2 = (((1.25*0.254) / 298) * 278) / 1.67

    V2=0.17736004501

    V2 = 0.177L
