    FAQ

    What is the molar mass of Se?

    M(Se) = 78.971 g/mol

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

    Only in units: the relative atomic mass Ar(Se) = 78.971 has no unit, and the molar mass M(Se) = 78.971 g/mol is the mass of one mole of atoms (6.022 × 10²³ of them).

    How many grams are in 2 moles of Se?

    m = n × M = 2 mol × 78.971 g/mol = 157.942 g.
