    Answer: 25.37055324733817mol

    Approximately 25.371mol

    Explanation: Number of moles of a substance is the mass of that substance containing the same amount of fundamental units, for instance atom in 12.0g of 12°C

    Therefore:

    Number of moles = mass / molecular mass

    Where mass of fluorine given = 482g

    Standard Molecular mass of fluorine = 18.9984032g/mol

    Substituting value in equation

    Mole = 482g/18.9984032g/mol = 25.37055324733817mol

    Approximately : 25.371mol
