QUESTIONS If 20.0 Cal make an ounce, how many ounces of formula should a baby drink per day if the energy need per day is 1.50 x 10³ Cal? Express answer to the correct number of significant figures. 75.0 x 10E3 QUESTION 3 A 9.86 g sample of iron metal was heated in water to 85°C. Then, it was dropped into a beaker containing 240.0 g of H₂O at 28.5°C. Assuming that the water gained all the heat lost by the iron, what is the final temperature of the H₂O and Fe? QUESTION 4 If 756 cal of heat were added to 64.8 g of Al at 32.5 °C, what is the final temperature of the aluminum?

*Note: For these problems, apply the principles of thermodynamics, specifically the concepts of heat transfer, to solve for unknown variables such as final temperature or mass. Consider using equations like \( q = mc\Delta T \) where \( q \) is the heat added or removed, \( m \) is the mass, \( c \) is the specific heat capacity, and \( \Delta T \) is the change in temperature.*](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F7c254fa5-9c5b-4da3-a7b1-67346d7992f7%2Fa15481a0-feb7-49af-badb-52121385a36f%2Fv6twhh7_processed.jpeg&w=3840&q=75)
