    FAQ

    What is the molar mass of Ca?

    M(Ca) = 40.078 g/mol

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

    Only in units: the relative atomic mass Ar(Ca) = 40.078 has no unit, and the molar mass M(Ca) = 40.078 g/mol is the mass of one mole of atoms (6.022 × 10²³ of them).

    How many grams are in 2 moles of Ca?

    m = n × M = 2 mol × 40.078 g/mol = 80.156 g.
