Determine the amount in grams of KCL that exist in 20.3g of a solution that contains 1.14 % KCL by mass. Please show work

Sagot :

Explanation:

The percent by mass of a solution is defined as the mass of solute divided by the mass of solution multiplied by 100.

mass % = mass of KCl/mass of solution * 100 = 1.14 %

We have to find the mass of KCl that exist in a 20.3 g of solution with a concentration of 1.14 % by mass.

20.3 g of solution * (1.14 g of KCl/100 g of solution) = 0.231 g of KCl

(20.3 g solution/1) * (1.14 g KCl/100 g solution) = 0.231 g KCl

Answer: there are 0.231 g of KCl
