What mass (g)of barium iodide is contained in 188 mL of a barium iodide solution that has an iodide ion concentration of 0.532 M?
A)19.6
B)39.1
C)19,600
D)39,100
E)276

Question

Quizplus · Accepted Answer

The correct answer is A because the mass of barium iodide can be calculated using the formula: mass = concentration x volume x molar mass. The molar mass of barium iodide is 391.19 g/mol. Therefore, the mass of barium iodide in 188 mL of a 0.532 M solution is: mass = 0.532 M x 188 mL x 391.19 g/mol = 19.6 g.
