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.
