The equation for this problem is q = (m)(delta T)(c), where q is the amount of heat energy absorbed, c is the specific heat, m is the mass, and delta T is the change in temperature. Rearranging this equation for the unknown in this problem yields m = q / ((delta T)(c)), substitute in the given information
m = (250 cal) / ((28 degrees C)(0.58 cal/(g*degrees C))
m = 15.4g
