    The volume will be 31, 55 ml

    Explanation:

    We use the gas formula, which results from the combination of the Boyle, Charles and Gay-Lussac laws. According to which at a constant mass, temperature, pressure and volume vary, keeping constant PV / T. We convert the unit Celsius into Kelvin:

    0 ° C = 273K, 50 ° C = 273 + 50 = 323K

    (P1x V1) / T1 = (P2xV2) / T2

    (0,5atm x 80ml) / 273K = (1,5 atmxV2) / 323K

    0,147 atmx ml/K = (1,5 atmxV2) / 323K

    V2 = (0,147 atmx ml/Kx 323K) / 1,5atm = 31,55 ml
