1. Determine the concentration of KCl in ppm when 4 mg of KCl is dissolved in 8mg of solution. ​

Sagot :

SOLUTION:

Step 1: List the given values.

[tex]\begin{aligned} & \text{mass of solute} = \text{4 mg} \\ & \text{mass of solution} = \text{8 mg} \end{aligned}[/tex]

Step 2: Solve for the concentration of KCl in ppm using the formula.

[tex]\begin{aligned} \text{parts per million} & = \frac{\text{mass of solute}}{\text{mass of solution}} \times 10^6 \\ & = \frac{\text{4 mg}}{\text{8 mg}} \times 10^6 \\ & = \boxed{\text{500,000 ppm}} \end{aligned}[/tex]

Hence, the concentration of KCl in ppm is 500,000 ppm
