Answer:
D. 27.099 x 10²³.
Explanation:
- It is known that every 1.0 mole of an atom contains Avogadro's no. (6.022 x 10²³) atoms.
<em>So, 4.5 mol of Hg will contain:</em>
(4.5 mol)(6.022 x 10²³) = 27.099 x 10²³ atoms.
<em>So, the right choice is: D. 27.099 x 10²³.</em>
If two shells overlap, they start to share electrons and thus, a bond is formed
Answer:
6 mass
Explanation:
because the si unit of gram is mass
Solute particles can be atoms, ions or molecules.
Explanation:
Solute is the material which has to be mixed in the solvent to prepare a solution. So the concentration of solute should be less than the solvent. Also the solute and solvent should be of same nature other they will not dissolve with each other. The solute can be made up of atoms, ions or molecules depending upon the solvent. If the solvent concentration is in moles, then the solute concentration can be taken as atoms, ions or molecules. Also the saturation point plays a main role in deciding the kind of particles taken for the solute.
