How is the density of a solid (insoluble in water) determined? but if the density of the water is less than that of the substances it sinks i know that but can you explain wheather is it the formula for law of flotation or for the density of the substances. we have different calculations for each substances to know the density,mass or weight of the folowing i know the formulas for weight,mass and to find the density of the folllowing qestions but just to conform please send me the anwer and kindly describe law of flotation and it uses law of flotation.The law of flotation is not only used to calculate the density buut it also have other uses as we know this why is pimosoll line  is in the hull of the ships is it used to calculate density i have heard in the book that it is used to measure density is it true and if i am right i have stated that if the density of the substance is less than that of thesubstance it sinks what is the word that mean. i am looking forward for your reply please reply
