In a lab experiment, a 0.6-g peanut is burned beneath 60 g of water. Heat from the burning peanut raises the water temperature from 22⁰C to 50⁰C in 3.0 minutes. If the heat transfer is 41% efficient, how many Calories of heat did the peanut release while burning? Show all calculations leading to an answer.
