Verified step by step guidance

Identify the chemical formula of each compound to determine the number of bromide ions each can produce. NaBr, CaBr2, AlBr3, and MnBr4 are the compounds in question.

For each compound, determine the number of bromide ions produced per formula unit. NaBr produces 1 Br⁻ ion, CaBr2 produces 2 Br⁻ ions, AlBr3 produces 3 Br⁻ ions, and MnBr4 produces 4 Br⁻ ions.

Calculate the concentration of bromide ions for each solution by multiplying the molarity of the solution by the number of bromide ions produced per formula unit. For example, for NaBr, the concentration of Br⁻ ions is 0.10 M * 1.

Perform the same calculation for each of the other solutions: CaBr2 (0.10 M * 2), AlBr3 (0.10 M * 3), and MnBr4 (0.05 M * 4).

Compare the calculated concentrations of bromide ions from each solution to determine which one has the highest concentration of bromide ions.
