merical value of the relative densitythe same as that of the specific gravity ? Why ? The density of a substance is one of its most im-portant characteristics. The knowledge of it is oftenindispensable, not only to the scientist, but also tothe manufacturer, merchant, and consumer. Findsome… … Purpose.—In this exercise it is proposed (cC) to determine the relative density of a wooden rod byapplying the principle of flotation,and (5) to determine the relativedensity of a liquid by using therod as a constant weight by hydrom-eter. Apparatus. — Qci) The rod ofwood whose relative density is…
