    V = 44.83 L

    Explanation:

    Given dа ta:

    Mass of fluorine = 76 g

    Temperature = 0°C

    Pressure = 101.3 Kpa

    Volume of fluorine = ?

    Solution:

    Temperature = 0°C (0°C + 273 = 273 K)

    Pressure = 101.3 Kpa (101.3 / 101 = 1 atm)

    First of all we will calculate the number of moles.

    Number of moles of F = Mass / molar mass

    Number of moles = 76 g / 38 g/mol

    Number of moles = 2 mol

    Volume of fluorine:

    Formula

    PV = nRT

    V = nRT / P

    V = 2 mol * 0.0821 atm. L / mol. k * 273 k / 1 atm

    V = 44.83 L. atm / 1 atm

    V = 44.83 L
