WebRelative Density. 1. A flat–bottomed test tube with some lead shots floats upright on the surface of water with 20 cm of its length immersed. The tube and lead shots were found to weigh 20 gf when weighed in a beam balance. The same test tube when floated in kerosene was found to float with 24 cm immersed. WebMar 31, 2024 · By Staff Writer Last Updated March 31, 2024. The formula for relative density is the quotient of the mass of the substance divided by the mass of the reference substance. The relative density can also be determined by finding the ratio of the weights in place of the density. The relative density formula calculates the density of the substance ...
WebApr 21, 2013 · Buoyant force is equal to the weight of water displaced so for the case of lead, the total force is then 45000g-3750g =41250g. For concrete, it is 45000g-18000g = 27000g. Thus, the 100 lb of lead "weighs" more than the 100 lb of concrete in water. However in both cases, the mass is the same 45 kg.
