nevsk [136]

Answer:

20ppm

Explanation:

parts per million are defined as the mass of solute in mg (In this case, mass of DDT) per kg of sample.

To solve this question we must find the mass of DDT in mg and the mass of sample in kg:

<em>Mass DDT:</em>

0.10g * (1000mg / 1g) = 100mg

<em>Mass sample:</em>

5000g * (1kg / 1000g) = 5kg

Parts per Million:

100mg / 5kg =

<h3>20ppm</h3>
