Bromine and Iodine are both
totally soluble in mineral oil because these substances are all made up of
non-polar molecules. And because water is a polar molecule, Bromine and Iodine
is not soluble in it.
Non polar solvents contain
bonds that have similar electronegativity, an example of this is carbon and
hydrogen such as gasoline. Some other examples are pentane, hexane, benzene
and toluene.

Answer:
Explanation:
To convert from grams to atoms, first divide by the molar mass, the multiply by 6.022*10^23.
To convert from moles to mass, multiply by the molar mass of the element.
Hope this helps!

Answer:
The proportion of dissolved substances in seawater is usually expressed in ppm, ppb or ppt
Explanation:
The concentration of very diluted solutions should be expressed in parts per million, billion or trillion.
ppm = mass from the solute . 10⁶ / mass or volume of the solution
ppb = mass from the solute . 10⁹ / mass or volume of the solution
ppt = mass from the solute . 10¹² / mass or volume of the solution
ppm = mg/kg, μg/g, μg/mL → These are the units
ppb = ng/g
ppt = pg/g
Ca because it has a larger atomic radius.
