Question

What mass (g) of barium iodide is contained in 154ml of a barium iodide solution

Answer 1

To calculate the mass of barium iodide, molarity and volume of the solution are needed. Unfortunately, the question doesn't provide molarity; hence the problem is unsolvable with the given information.

Step-by-step explanation:

To find the mass of barium iodide in a solution, one would typically need to know the concentration of the barium iodide in the solution (molarity). However, the question does not provide this crucial piece of information. Assuming that we had the molarity, we would use the formula:

1. 
   
3. Calculate the number of moles of barium iodide using the volume of the solution and the molarity (Moles = Molarity × Volume in liters).
4. 
   
6. Calculate the mass of barium iodide by multiplying the number of moles by the molar mass of barium iodide (Mass = Moles × Molar Mass).

Without the molarity info, the problem cannot be solved.
