    FAQ

    What is the molar mass of Ba?

    M(Ba) = 137.33 g/mol

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

    Only in units: the relative atomic mass Ar(Ba) = 137.33 has no unit, and the molar mass M(Ba) = 137.33 g/mol is the mass of one mole of atoms (6.022 × 10²³ of them).

    How many grams are in 2 moles of Ba?

    m = n × M = 2 mol × 137.33 g/mol = 274.66 g.
