1. The problem statement, all variables and given/known data A solid block is attached to a spring scale. The reading on the scale when the block is completely immersed in water is 25.2 N, and the reading when it is completely immersed in alcohol of density 806 kg/m^3 is 25.9 N. 2. Relevant equations F buoyancy = (Density of the liquid) x (Volume of the liquid displaced) x g F Gravity = (Density of the object) x (Volume of the object) x g F total = F buoyancy - F Gravity F total = ((Density of the liquid)x(Volume of the liquid displaced)-(Density of the object)x (Volume of the object))g 3. The attempt at a solution I assumed that Density of water was 998kg/m^3 I discussed this with my physics professor, he told me to "subtract the two F total equations from on another." I did so, and found that the Volume of the displaced water = .80763xVolume of the displaced alcohol. However, i do now see how this helps me determine the volumes of the mass in solution. All of my continued efforts result in me ending up with too many unknowns. Without the mass of the object, or its density, or the volume of liquid displaced (to find the buoyant force), I'm just stuck. Thanks for your time and effort, Long time reader, first time poster.
