Answer:
[tex]ppth=1.2ppth[/tex]
Explanation:
Hello!
In this case, since the parts per thousand of a solute in a solute is defined in terms of its grams per kilogram of solution (unlike parts per million which are mg/kg) we can mathematically represent it via:
[tex]ppth=\frac{grams_{solute}}{kg{solution}}[/tex]
Now, since the whole human body acts as the solution and the chlorine in the form of ions as the solute, the required ppth turns out:
[tex]ppth=\frac{84.0g}{70.0kg}\\\\ppth=1.2ppth[/tex]
Best regards!
