A fan jumps into a swimming pool in an attempt to drown her sorrows. She is able to float on her back...in a position that is neutrally buoyant...so that she can continue to breathe through her mouth. Believing that 70% of her body is composed of water and 20% is composed of denser materials (bones, teeth, etc.) with a specific gravity of 1.25, what is the specific gravity of the remaining 10% of her body/internal composition? (Specific gravity is just the ratio of density of a material to water. Thus, a specific gravity of 1.25 corresponds to a density of.)
