Answer:

Explanation:
The formula for the amount of heat absorbed by a substance is
q = mCΔT
Thus, the three factors are the
- mass
- specific heat capacity
- temperature change
The only factor that is on your list is

The shape of the substance has no effect, nor do its melting and boiling points.
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>
