1) find the molar mass of MgCl2 = 95.211 2) calculate the no. of moles = mass/molar mass = 9.53/95.211= 0.100093476 3) multiply the no. of moles by the no. of ions, there are 3 ions So, 0.100093476 * 3 = 0.300280429 4) now, multiply this answer by the Avogadro's constant and you get 1.81 x 10^23

Although electrons were sent one by one, interference fringes could be observed. These interference fringes are formed only when electron waves pass through on both sides of the electron biprism at the same time but nothing other than this. Whenever electrons are observed, they are always detected as individual particles.
These atoms are attracted by other similar atoms by van der Waal’s force of attraction and thus form small metallic particles. This is how both ions and particles are produced by the electrolysis process. Typically 90% of the silver leaving the anode stays in the ionic form while about 10% forms into particles.
The number of ions in a compound depends on the structure of the compound and the oxidation states of the elements within the compound . An element’s oxidation state is the number of electrons that an atom possesses or lacks relative to the number of protons in its nucleus.
The Lewis structure for CO has 10 valence electrons. For the CO Lewis structure you’ll need a triple bond between the Carbon and Oxygen atoms in order to satisfy the octets of each atom while still using the 10 valence electrons available for the CO molecule.
Any elements in Group 14, also known as the carbon group , will have four valence electrons. This group contains carbon, silicon, geranium, tin, lead, and flerovium . These elements are all in the same group precisely because of the same number of valence electrons.
