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.
There are 0.021 moles of MgBr2 in 3.50 g. Since MgBr2 contains 2 bromide ions per formula unit, there are 0.042 moles of Br- ions. So, there are 0.042 * 6.022 x 10^23 = 2.53 x 10^22 Br- ions in 3.50 g of MgBr2.
Magnesium bromide has the chemical formula MgBr2. It is composed of one magnesium ion (Mg2+) and two bromide ions (Br-).
The "2" in MgBr2 indicates that magnesium (Mg) forms an ionic compound with two bromide ions (Br-). This means that magnesium will have a 2+ charge to balance the 2- charge of the two bromide ions.
MgBr2 is an ionic compound. Ionic compounds are formed through the transfer of electrons between a metal and a non-metal, resulting in attraction between positively and negatively charged ions. In the case of MgBr2, magnesium (metal) loses two electrons to bromine (non-metal), forming Mg2+ and 2Br- ions.
The ionic formula for Mg and Br is MgBr2, with magnesium having a 2+ charge and bromine having a 1- charge. MgBr2 indicates that two bromide ions combine with one magnesium ion in the compound.
There are 1.35 moles of MgBr2 in 1 L of solution, which corresponds to 2 moles of bromide ions. Therefore, in 750.0 mL of 1.35 M MgBr2 solution, there will be 1.0125 moles of bromide ions.
There are 0.021 moles of MgBr2 in 3.50 g. Since MgBr2 contains 2 bromide ions per formula unit, there are 0.042 moles of Br- ions. So, there are 0.042 * 6.022 x 10^23 = 2.53 x 10^22 Br- ions in 3.50 g of MgBr2.

In MgBr2, there are two bromide anions (Br-) for each magnesium cation (Mg2+), so the total number of anions in MgBr2 is 2.
Is the following chemical equation balanced? MgI2 + Br2 MgBr2 + I2 yes no
The molar mass of MgCl2 = 95.211 g/mol
MgBr2 will cause the bulb to glow brightly as it is an ionic compound and produces two ions per molecule . On the other hand, CH3OH is an organic compoound which is merely dissolved in water due to intermoleculer hydrogen bonding and is not a good electrolyte!
