    (a) 0.047 g (b) 0.0016 oz (c) 0.0001 lb

    Explanation:

    The given mass of the sodium in the slice = 47 mg

    (a) Mass has to be calculated in grams

    The conversion of mg to g is shown below as:

    1 mg = 10⁻³ g

    So,

    Mass of sodium = 47 * 10⁻³ g = 0.047 g

    (b) Mass has to be calculated in ounces

    The conversion of ounces to g is shown below as:

    453.6 g = 16 oz

    Or,

    1 g = 16 / 453.6 oz

    So,

    Mass of sodium = (0.047 * 16) / 453.6 oz = 0.0016 oz

    (c) Mass has to be calculated in pounds

    The conversion of pounds to g is shown below as:

    1 lb = 453.6 g

    Or,

    1 g = 1 / 453.6 lb

    So,

    Mass of sodium = (0.047 * 1) / 453.6 oz = 0.0001 lb
