    Molar mass of boron = 10.8 gmol-1

    The conversion factor to convert mass of boron to moles of boron is the molar mass of boron

    0.034 moles of boron

    Explanation:

    Molar mass of boron = 10.8 gmol-1

    We know that;

    Number of moles = mass/molar mass

    We already know the molar mass of boron as 10.8 gmol-1. The given mass of boron according to the question is 3.70 x 10^-1 g.

    From our formula;

    Number of moles = 3.70 x 10^-1 g / 10.8gmol-1

    Number of moles = 0.034 moles of boron
