A person eats a container of yogurt. The Nutritional Facts label states that it contains 195 Calories (1 Calorie = 4186 J). What mass of perspiration would one have to lose to get rid of this energy? At body temperature, the latent heat of vaporizaiton of water is 2.42 106 J/kg.
check your units, and solve for the mass of water.
