In MgBr2, there are two bromide anions (Br-) for each magnesium cation (Mg2+), so the total number of anions in MgBr2 is 2.
The molar mass of MgCl2 = 95.211 g/mol
The chemical formula of magnesium dibromide is MgBr2.
The reaction between Mg and Br2 results in the formation of MgBr2. The balanced chemical equation is: Mg + Br2 → MgBr2
MgBr2 is an ionic compound (salt: magnesium bromide)

Magnesium (Mg) and Bromine (Br) - Magnesium Bromide - MgBr2
Is the following chemical equation balanced? MgI2 + Br2 MgBr2 + I2 yes no
The molar mass of MgCl2 = 95.211 g/mol
Magnesium bromide
The chemical formula of magnesium dibromide is MgBr2.
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.
The reaction between Mg and Br2 results in the formation of MgBr2. The balanced chemical equation is: Mg + Br2 → MgBr2
There are a total of 2 moles of anions in 2.50 g of MgBr2. Each formula unit of MgBr2 contains 2 moles of anions (Br-). The molar mass of MgBr2 is 184.113 g/mol, so 2.50 g is equivalent to 0.0136 moles, and therefore 0.0136 moles * 2 moles = 0.0272 moles of anions.
MgBr2 is soluble in water and other polar solvents.
MgBr2 is an ionic compound (salt: magnesium bromide)
The answer is 5,978 moles.
