A . O2- because it is a negatively charged ion
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>
And the answer is False,it does not have the same number with particles as the one mole of hydrogen.
Answer:
0.682L or 682mL
Use Charles Law of V1/T1 = V2/T2
V1 = 0.6L
T1 = 293K
V2=?
T2= 333K
