Answer:
0.23 g
Explanation:
From the question given above, the following data were obtained:
Mass of solution = 20.3 g
Percentage by mass of KCl = 1.14%
Mass of KCl =?
The mass of KCl in the solution can be obtained as follow:
Percentage by mass = mass of solute / mass of solution × 100
1.14% = mass of KCl / 20.3
Cross multiply
Mass of KCl = 1.14% × 20.3
Mass of KCl = 1.14/100 × 20.3
Mass of KCl = 0.0114 × 20.3
Mass of KCl = 0.23 g
Therefore, the mass of KCl in the solution is 0.23 g
