Question

Determine the amount in grams of kcl that exists in 20.3 g of a solution that contains 1.14 % KCI by mass.

Answer 1

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
