Question

1. What is the mass in grams of potassium iodide in 14.86 ml of a 32.44% mass by volume of an aqueous potassium iodide solution.
2. A student was provided with an aqueous solution of sodium chloride solution of 11.78% mass by volume. If 1.22 of sodium chloride is added to make the solution, then what must be the volume of this solution?

Answer 1

Explanation:

The concentration of potassium iodide solution = 32.44 % w/v

The concentration of potassium iodide solution = 32.44 % w/vThe volume of potassium iodide solution = 14.86 ml

The concentration of potassium iodide solution = 32.44 % w/vThe volume of potassium iodide solution = 14.86 mlTo Find:

The concentration of potassium iodide solution = 32.44 % w/vThe volume of potassium iodide solution = 14.86 mlTo Find:The mass in grams of potassium iodide in the given volume of solution.

The concentration of potassium iodide solution = 32.44 % w/vThe volume of potassium iodide solution = 14.86 mlTo Find:The mass in grams of potassium iodide in the given volume of solution.Calculation:

The concentration of potassium iodide solution = 32.44 % w/vThe volume of potassium iodide solution = 14.86 mlTo Find:The mass in grams of potassium iodide in the given volume of solution.Calculation:- According to the question:

The concentration of potassium iodide solution = 32.44 % w/vThe volume of potassium iodide solution = 14.86 mlTo Find:The mass in grams of potassium iodide in the given volume of solution.Calculation:- According to the question:Concentration = 32.44 % w/v

The concentration of potassium iodide solution = 32.44 % w/vThe volume of potassium iodide solution = 14.86 mlTo Find:The mass in grams of potassium iodide in the given volume of solution.Calculation:- According to the question:Concentration = 32.44 % w/v⇒ The mass of KI in 100 ml of solution = 32.44 gm

The concentration of potassium iodide solution = 32.44 % w/vThe volume of potassium iodide solution = 14.86 mlTo Find:The mass in grams of potassium iodide in the given volume of solution.Calculation:- According to the question:Concentration = 32.44 % w/v⇒ The mass of KI in 100 ml of solution = 32.44 gm⇒ The mass of KI in 14.86 ml of solution = (32.44/100) × 14.86

The concentration of potassium iodide solution = 32.44 % w/vThe volume of potassium iodide solution = 14.86 mlTo Find:The mass in grams of potassium iodide in the given volume of solution.Calculation:- According to the question:Concentration = 32.44 % w/v⇒ The mass of KI in 100 ml of solution = 32.44 gm⇒ The mass of KI in 14.86 ml of solution = (32.44/100) × 14.86⇒ The mass of KI in 14.86 ml of solution = 4.82 gm

The concentration of potassium iodide solution = 32.44 % w/vThe volume of potassium iodide solution = 14.86 mlTo Find:The mass in grams of potassium iodide in the given volume of solution.Calculation:- According to the question:Concentration = 32.44 % w/v⇒ The mass of KI in 100 ml of solution = 32.44 gm⇒ The mass of KI in 14.86 ml of solution = (32.44/100) × 14.86⇒ The mass of KI in 14.86 ml of solution = 4.82 gm- So, the mass of potassium iodide in the given volume of solution is 4.82 gm.
