    FAQ

    What is the molar mass of As?

    M(As) = 74.922 g/mol

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

    Only in units: the relative atomic mass Ar(As) = 74.922 has no unit, and the molar mass M(As) = 74.922 g/mol is the mass of one mole of atoms (6.022 × 10²³ of them).

    How many grams are in 2 moles of As?

    m = n × M = 2 mol × 74.922 g/mol = 149.844 g.
