    Answer: v2=331.289mL

    Explanation:

    Formula for ideal gas law is p1v1/T1=p2v2/T2

    P1=782.3mmHg

    P2=769mmHg at STP

    V1=362.4mL

    V2=?

    T1=273+34.4=307.4k

    T2=273k at STP

    Then apply the formula and make v2 the subject of formula

    V2 = 782.3*362.4*273/760*307.4

    V2=77397006.96/233624

    V2=331.289mL
