When my son weighed 15.1 kg I put him into a bathtub containing 55.0 gallons of water when filled to the very top. After I put him in, I collected all the water that ran over the side of the tub, and found it to be equal to 3.65 L.
(A) What is the density of my son in grams per cubic centimeter?
(B) What if next time I do this he gains 2.25 kg. and grows big enough to displace 6.11 L. Will he still have the same density? Explain and prove your answer.
