Calculate the concentration of a solution prepared by dissolving 10.2 g of Ba(OH)₂ in water to make a 350.0 mL solution. Report the concentrations in molarity and normality.

• A. molarity = 0.188 M
  normality = 0.188 N
• B. molarity = 0.188 M
  normality = 0.376 N
• C. molarity = 0.170 M
  normality = 0.170 N
• D. molarity = 0.170 M
  normality = 0.340 N

Answer: (D)
