    FAQ

    What is the molar mass of Pb?

    M(Pb) = 207.2 g/mol

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

    Only in units: the relative atomic mass Ar(Pb) = 207.2 has no unit, and the molar mass M(Pb) = 207.2 g/mol is the mass of one mole of atoms (6.022 × 10²³ of them).

    How many grams are in 2 moles of Pb?

    m = n × M = 2 mol × 207.2 g/mol = 414.4 g.
