The formula to calculate the amount of heat (in calories) absorbed by a substance when its temperature is raised is:

Q = m * c * ΔT

where Q is the amount of heat absorbed, m is the mass of the substance, c is the specific heat of the substance, and ΔT is the change in temperature.

Substituting the given values:

Q = 13 g * 0.588 cal/g °C * (23 °C - 11 °C)
Q = 13 g * 0.588 cal/g °C * 12 °C
Q = 92.304 cal

Therefore, the answer is choice C: 92 cal.
