<span>Avogadro's number
represents the number of units in one mole of any substance. This has the value
of 6.022 x 10^23 units / mole. This number can be used to convert the number of
atoms or molecules into number of moles.
45.6 g Au ( 1 mol / 196.97 g ) ( </span>6.022 x 10^23 atoms / mole ) = 1.39x10^23 atoms Au
I would pick either b) or D) but you just have to remember that not all ionicbonds will bond together, because some bonds are only negattive bonds,
They have free electron(s) on their outermost energy levels making them good conductors.
They have metallic bonds in their chemical structure.
They readily lose the electrons on their outermost energy levels, to bond with non-metals in ionic bonds to form chemical compounds called "salts"
