Final answer:
The mass of potassium iodide in a 50.0 ml solution depends on the concentration of the solution.
Step-by-step explanation:
The mass of potassium iodide in a 50.0 ml solution can be calculated using the formula:
Mass (g) = Volume (ml) x Concentration (g/ml)
In this case, we need to know the concentration of the potassium iodide solution. Without this information, we cannot calculate the mass of the solute. Please provide the concentration of the solution in order to answer the question accurately.
