1.2 equivalents
There are 1.20 equivalents in 0.60 mole of Mg2+, since Mg2+ has a charge of 2+.
This is a basic stoichiometry question. Things you need to know:1 mol = 6.022 x 10^23 atoms/particles/molecules/ionsRatio of Mg in MgCl2 : 1mol Mg2+/1 mol MgCl2Always start with what you are given:3.00 mol MgCl2 X 1mol Mg2+/1 mol MgCl2 X 6.022 x 10^23 ions Mg2+/ 1mol Mg2+=1.8066 x 10^24 ions Mg2+
Mg2+ + 2 Cl- are in 1 : 2 ratio (of ions) so also 0.25 : 0.50 mole ratio
No, 1 mole of NaCl will produce 2 ions (1 Na+ and 1 Cl-) while 1 mole of MgCl2 will produce 3 ions (1 Mg2+ and 2 Cl-), so they do not have an equal number of ions.
One formula unit of MgBr2 has three ions; one Mg2+ ion and two Br- ions. One mole of MgBr2 formula units has one mole of Mg2+ ions and two moles of Br- ions, for a total of three moles of ions.
An Mg2+ ion is a magnesium ion that has a charge of +2, meaning it has lost 2 electrons. The number of neutrons in an Mg2+ ion is the same as in a regular magnesium atom, which is 12 neutrons.
Mg2+: [1s22s22p6]
The cation for MgCl2 is Mg2+.

An Mg2+ ion has lost two electrons, resulting in a total of 10 electrons. Magnesium normally has 12 electrons but when it forms a 2+ ion, it loses two electrons.
There are 10 electrons in Mg2+ because the atomic number of magnesium is 12, which means it normally has 12 electrons. When it forms a 2+ ion, it loses 2 electrons, leaving 10 electrons in the Mg2+ ion.
