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) 37.7
E) 0.048

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 391.14 g/mol. Therefore, the mass of barium iodide in 250 mL of a 0.193 M solution is: mass = 0.193 M x 0.250 L x 391.14 g/mol = 9.44 g.
