What is the concentration of NO₃^- ions in a solution prepared by dissolving 15.0 g of Ba(NO₃)₂ in enough water to produce 300.mL of solution? A)0.057 M B)0.191 M C)0.573M D)0.382 M

Question

Quizplus · Accepted Answer

The molar mass of Ba(NO3)2 is approximately 261.34 g/mol. Dissolving 15.0 g in 300 mL (0.3 L) gives a concentration of 0.191 M for Ba(NO3)2. Since each formula unit produces two NO3- ions, the concentration of NO3- ions is 0.191 M * 2 = 0.382 M.
