We are given that 1 teaspoon is equivalent to 5 mL,
therefore 0.75 teaspoon is:
0.75 teaspoon * (5 mL / 1 teaspoon) = 3.75 mL
So the mass is density times volume:
mass = (12.5 mg/5 ml) * 3.75 mL
<span>mass = 9.375 mg</span>

The layer that doesn't exist at all is the l<u>ithosphere</u> because the very last level of the entire atmosphere is the exosphere.
An ionic bond is a bond which occurs when there is a

atom hence making it more negative (anion), while the other becomes a cation.
So answer is:
<span>b. a cation and an anion</span>
