how many grams of KCL are there in 1200 ml of a 2% KCI solution

To determine the number of grams of KCl in the given solution, you need to follow these steps:

Step 1: Convert the volume of the solution from milliliters (ml) to grams (g) using the density of the solution. However, since the density is not provided, we will assume that the solution has the same density as water, which is approximately 1 g/ml. So, 1200 ml of solution is equal to 1200 g.

Step 2: Calculate the mass of KCl in the solution based on the given concentration. A 2% KCl solution means that there are 2 grams of KCl per 100 grams of solution. We can represent this concentration as a ratio: 2/100 = 0.02.

Step 3: Multiply the mass of the solution (1200 g) by the concentration ratio (0.02) to find the mass of KCl in the solution.

Mass of KCl = 1200 g * 0.02 = 24 g

Therefore, there are 24 grams of KCl in 1200 ml of a 2% KCl solution.
