What mass (g)of barium iodide is contained in 250 mL of a barium iodide solution that has an iodide ion concentration of 0.193 M?
A)9.44
B)18.9
C)0.024
D)0.048
E)37.7

Question

Quizplus · Accepted Answer

The correct answer is A because the mass of barium iodide can be calculated using the formula: mass = concentration * volume * molar mass. The molar mass of barium iodide is 391.15 g/mol. So, mass = 0.193 M * 0.250 L * 391.15 g/mol = 9.44 g.
