d. A calorimeter has mass 100 g and specific heat \( 0.1 \mathrm{kcal} / \mathrm{kg}{ }^{\circ} \mathrm{C} \). It contains 250 gm of liquid at \( 30{ }^{\circ} \mathrm{C} \) having specific heat of \( 0.4 \mathrm{kcal} / \mathrm{kg} \) \( { }^{\circ} \mathrm{C} \). If we drop a piece of ice of mass 10 g at 0 . C , What will be the temperature of the mixture?
