Out of the options, glass is the least fluid. The proof of this also lies in the fact that glass is the most difficult to melt out of all of the mentioned substances, and melting point gives us a rough estimate of the strength of intermolecular forces.
For the Lewis diagram of the cyanide ion, a
figure is shown.<span>
There are 3 pairs of bonding electrons. There is a
one lone pair each for the carbon and the nitrogen atoms.</span>

Answer:
a. 0.191 ppm b. 4.962 ppm c. 0.0385 ppm
Explanation:
a. 17 g of calcium = 0.017 mg. 89 mL = 0.089 L.
So our concentration = 0.017 mg/0.089 L = 0.191 mg/L = 0.191 ppm
b. 0.65 mg of caffeine in 131 mL = 0.131 L.
So our concentration = 0.65 mg/0.131 L = 4.962 mg/L = 4.962 ppm
c. 0.35 mg of trace particle in 91 dL = 9.1 L.
So our concentration = 0.35 mg/9.1 L = 0.0385 mg/L = 0.0385 ppm
