Answer: B) 12.5
Explanation: I looked REALLY REALLY close
(It hurt my eyes but whatever)
<span>V = 150.0 mL = 0.15 L
c = 1.70 M
</span>m=?
For the purpose, the equation for molar concentration is necessary:
c=n/V
From the equation we can determine the number of moles:
n= cxV = 1.70M x 0.15L = 0.255 mole
Now we can calculate the mass:
m = nxM = 0.255 x 119= 30.34 g is necessary
Answer:
Cold Waves
Explanation:
Cold Waves -
This type of wave are used to curl the hairs without the application of any type of heat and along with it , thioglycolic acid or any of its derivatives are used along with ammonia , during the process of curling .
