What is the concentration in ppm of a solution in which 0.0049 g of KCl ) has been dissolved, making a solution with a volume of 650 mL

Sagot :

SOLUTION:

Step 1: List the given values.

Note that the volume of solution should be expressed in milliliters (mL).

[tex]\begin{aligned} & \text{volume of solution} = \text{650 mL} \\ & \text{mass of solute} = \text{0.0049 g} \end{aligned}[/tex]

Step 2: Calculate the concentration of the solution in ppm.

[tex]\begin{aligned} \text{parts per million} & = \frac{\text{mass of solute}}{\text{volume of solution}} \times 10^6 \\ & = \frac{\text{0.0049 g}}{\text{650 mL}} \times 10^6 \\ & = \boxed{\text{7.5 ppm}} \end{aligned}[/tex]

Hence, the concentration of a solution is 7.5 ppm.
