Answer 2

Answer:

Its concentration is 10 ppm.

Option d is the correct answer.

Explanation:

Given, Mass of NaCl is 10 g

Mass of solution is 10⁶g

$ppm = \frac{mass \: of \: solute}{mass \: of \: solution} \times {10}^{6}$

Here mass of solute means mass of NaCl.

Mass fraction

$= \frac{10}{260}$

Now

$ppm = \frac{10}{ {10}^{6} } \times {10}^{6}$

$ppm = 10$

Its concentration is 10 ppm.

$ppm = parts \: per \: million$
