    P = 0.0373 atm

    Explanation:

    Given dа ta:

    Mass of krypton = 1.86 g

    Volume of krypton = 17.5 L

    Temperature of krypton = 190 F

    Pressure of krypton = ?

    Solution:

    First of all we will calculate the number of moles.

    Number of moles = mass / molar mass

    Number of moles = 1.86 g / 83.9 g/mol

    Number of moles = 0.022 mol

    Formula:

    PV = nRT

    P = nRT / V

    P = 0.022 mol * 0.0821 atm. L. mol⁻¹. K⁻¹ * 360.928 K / 17.5 L

    P = 0.652 atm. L / 17.5 L

    P = 0.0373 atm
