    P = 28.1 atm

    Explanation:

    Given dа ta:

    Mass of carbon dioxide = 25 g

    Temperature = 27.0 °C

    Volume = 500 mL

    Pressure = ?

    Solution:

    Number of moles = mass / molar mass

    Number of moles = 25.0 g / 44 g/mol

    Number of moles = 0.57 mol

    PV = nRT

    P = nRT/V

    P = 0.57 mol * 0.0821 atm. L. mol⁻¹. K⁻¹ * 300 k / 0.5 L

    P = 14.1 atm. L / 0.5 L

    P = 28.1 atm
