    Answer:

    T° = 453.6 K

    Explanation:

    Let’s apply the Ideal Gases Law to solve the question:

    Pressure . Volume = number of moles . R . T°

    We replace data:

    5.5 atm . 35.3L = 5.2 mol . 0.082 L.atm/mol.K .T°

    T° = (5.5 atm . 35.3L) / (5.2 mol . 0.082 L.atm/mol.K)

    T° = 453.6 K

    The Ideal Gases Law contains the Absolute value of T° (Kelvin degrees)

    So the final answer is: 453.6 K

    You can also determine this, because the unit of R (Ideal Gases constant)
