    FAQ

    What is the molar mass of B?

    M(B) = 10.81 g/mol

    How is the molar mass of boron different from its atomic weight?

    Only in units: the relative atomic mass Ar(B) = 10.81 has no unit, and the molar mass M(B) = 10.81 g/mol is the mass of one mole of atoms (6.022 × 10²³ of them).

    How many grams are in 2 moles of B?

    m = n × M = 2 mol × 10.81 g/mol = 21.62 g.
