Determine the amount of potassium chloride in each of the following solutions: 21.7g of a solution containing 1.10% KCl by mass.

To determine the amount of potassium chloride (KCl) in a solution, you can use the given mass percentage and the total mass of the solution. Here's how you can calculate it:

Step 1: Convert the percentage to a decimal fraction.
Percentage = 1.10% = 1.10/100 = 0.0110

Step 2: Calculate the mass of KCl in the solution.
Mass of KCl = Mass of solution × Percentage of KCl
Mass of KCl = 21.7 g × 0.0110
Mass of KCl = 0.2387 g (rounded to four decimal places)

Therefore, there is approximately 0.2387 grams of potassium chloride (KCl) in the given solution containing 21.7 grams.
