    4.0g Hg. I may be wrong and I really don't remember how to do it so I am not going to tell you my work, but I tried because I never did good on the chapter in chem.

    The number of moles in a substance indicates the amount of the substance that contains the same number of particles as 12 g of the Carbon-12 isotope [or equivalent to 6.02 * 10²³] (which is used as a standard in the world of moles).

    Now,

    if 6.02 * 10²³ atoms are found in 1 mole of mecury

    then let 1.20 * 10²² atoms are found in x

    ⇒ x = (1.20 * 10²²) : (6.02 * 10²³)

    = 0.0199 moles

    Now, mass = moles * molar mass

    ∴ mass of Hg = 0.0199 mol * 201 g/mol

    = 4.001 g

    ∴ T he mass in grams of a sample of 1.20 x 10 ²² atoms of mercury is ~ 4 g
