Answer:
= 25 ppm
Explanation:
- PPM also refers to parts per million, it represents a low concentration of a solution. It represents 0.001 gram or a milligram in a 1000 mL, which equivalent to 1 mg per liter.
Given; a sample size of 2000 g contained 0.050 g DDT
It means, 2000 mL sample contained 50 mg DDT
Therefore in ppm we get;
= 50 mg/ 2 L
= 25 mg/L
<u>= 25 ppm</u>
The object will speed up and start to spin in different directions.
<span>Since Carbon has a chemical name of "C," Hydrogen has "H" and Oxygen has O, we can start with the name "CHO". After this, the next task is to place the proper numbers next to the proper elements. In this case, the representation would be C(6)H(12)O(6), which would be the representation of the simple sugar glucose.</span>
